Comparison of single cell responses of antennal sensilla trichodea in the nine European small ermine moths (Yponomeuta spp.) was written by Van der Pers, J. N. C.. And the article was included in Entomologia Experimentalis et Applicata in 1982.Name: (E)-Dodeca-9,11-dien-1-yl acetate The following contents are mentioned in the article:

Single cell recordings were made from antennal sensilla trichodea of males of the 9 European small ermine moths by the tip-recording technique. Seventeen chem. were used as stimuli. Two or 3 electrophysiol. types of sensilla trichodea were found in each species. The response spectra of the receptor cells in these sensilla differed both intra- and interspecifically. Most cell types were sensitive to ≥2 substances, but some types were activated by one substance only. The results suggest that the various species use different multicomponent female sex pheromones. cis-11-Tetradecen-1-ol-acetate and trans-11-tetradecen-1-ol acetate are common components of these pheromones. Reproductive isolation in Yponomeuta may be maintained by different blends of these substances and/or the presence of addnl. compounds This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Name: (E)-Dodeca-9,11-dien-1-yl acetate).

(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Name: (E)-Dodeca-9,11-dien-1-yl acetate

Synthesis of 12-acetoxy-1,3-dodecadiene, an insect sex pheromone of the red bollworm moth, from a butadiene telomer was written by Mandai, T.;Yasuda, H.;Kaito, M.;Tsuji, J.;Yamaoka, R.;Fukami, H.. And the article was included in Tetrahedron in 1979.Quality Control of (E)-Dodeca-9,11-dien-1-yl acetate The following contents are mentioned in the article:

Selective hydroboration of R(CH₂)₃CH:CHCH₂OPh (I; R = CH₂:CH), prepared in 78% yield by Pd-catalyzed telomerization of butadiene with PhOH, followed by H₂O₂ oxidation, gave 80% I (R = HOCH₂CH₂). Tosylation (84%) of the latter followed by treatment with NaI in refluxing Me₂CO gave 95% I (R = ICH₂CH₂). Grignard reaction of the latter with RO(CH₂)₄MgCl (R = tetrahydropyranyl) gave 80% RO(CH₂)₉CH:CHCH₂OPh (II; R as before), which after hydrolysis and acetylation gave II (R = AcO). The title pheromone was obtained (71%) by Pd-catalyzed elimination of PhOH from II (R = AcO).

(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Multivariate analysis of the correlation between noctuidae subfamilies and the chemical structure of their sex pheromones or male attractants was written by Renou, Michel;Lalanne-Cassou, Bernard;Michelot, Didier;Gordon, Ginette;Dore, Jean Christophe. And the article was included in Journal of Chemical Ecology in 1988.HPLC of Formula: 50767-78-7 The following contents are mentioned in the article:

Female-emitted pheromones and sex attractants of Noctuidae were investigated by using a specific computer procedure to analyze data collected from the literature. Correspondence anal. was used to survey the structure-activity relationships of sex pheromones in 7 subfamilies. Structural, stereochem., and functional features of active mols. were related to taxonomy. This multidimensional anal. revealed that the prevalent chem. frame of noctuid moth pheromones was a monosatd. acetate with Z stereochem. and a double bond on the 5th carbon closest to the nonfunctional branch of the mol. Possible phylogenetic relationships within Noctuidae and between Noctuidae and other families are discussed in light of the sex pheromone biochem. Female sex pheromones appeared to be an addnl. character to be considered in the classification of noctuid moths. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7HPLC of Formula: 50767-78-7).

(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.HPLC of Formula: 50767-78-7

And the article was included in Journal of Chemical Ecology in 1981.Quality Control of (E)-Dodeca-9,11-dien-1-yl acetate The following contents are mentioned in the article:

Two compounds identified as components of the sex pheromone system of R. frustrana are (E)-9-dodecen-1-yl acetate (I) [35148-19-7] and (E)-9,11-dodecadien-1-yl acetate (II) [50767-78-7], which were found in female gland extracts in the ratio of 96:4, resp. The identifications were based on chem. and instrumental anal., electroantennogram studies, and field trapping tests. The optimum ratio for trapping male R. frustrana was from 95:5 to 97.5:2.5 (I:II), when dispensed from rubber septa at a loading of âˆ?000 μg/lure. In addition to these 2 compounds, evidence was obtained for the presence of dodecan-1-ol [112-53-8] and (E)-9-dodecen-1-ol [35237-62-8] in female tip extracts and in female effluvium, and for dodecan-1-yl acetate [112-66-3] in female tip extracts This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Quality Control of (E)-Dodeca-9,11-dien-1-yl acetate).

Assignment of configurations of conjugated dienic pheromones by fuzzy classification of carbon-13 chemical shifts was written by Zhang, Youjie;Huang, Wenfang;Zhu, Jun. And the article was included in Analytica Chimica Acta in 1990.Safety of (E)-Dodeca-9,11-dien-1-yl acetate The following contents are mentioned in the article:

The configurations of conjugated dienes, and some sex pheromones and analogous compounds, can be characterized by a fuzzy classification method applied to the ¹³C chem. shifts of the dienic carbons. A fuzzy relation matrix of 12 model dienes is set up, and a fuzzy parameter (λ) is established. If λ â‰?.95 in the similarity test of two dienes, then both dienes have the same configuration. Some empirical rules dealing with the influence of terminal groups and assignment of the order of dienic carbons are presented. Configurations of 14 compounds prepared by different methods were established reliably. After correct assignments of dienic carbons, the method was used to quantify the isomeric composition of (10,12)-pentadecadienyl acetate, (9,11)-tridecadienyl acetate and (9,11)-tetradecadienyl acetate by the inverted gated decoupling technique; the results agreed well with those obtained by gas chromatog.

Na 2-thiophenetellurolate (I), generated in catalytic amounts from bis(2-thienyl) ditelluride by NaBH₄, debrominated 1,4-dibromo-2-olefins, e.g., BrCH₂CH:CHCHRBr [II, R = Et, Bu, Me(CH₂)_n, AcO(CH₂)_m; n = 6, 8; m = 7, 8] to 1,3-dienes under mild conditions. The required II were prepared by allylic α,α’-bromination of olefins by N-bromosuccinimide. Terminal olefins yielded, via allylic rearrangement, a mixture of II and 1,2-dibromo-3-olefins. Both isomers were converted to 1,3-dienes (E/Z â‰?9/1) by I. The synthetic utility of the tellurolate-induced debromination was demonstrated in a 2-step synthesis of (E)-CH₂:CHCH:CH(CH₂)₈OAc, the main component of the red bollworm moth sex pheromone.

Sex pheromone of the sugarcane shoot borer, Tetramoera schistaceana Snellen (Lepidoptera:Tortricidae:Olethreutinae). Isolation and identification was written by Kinjo, Mieko;Nagamine, Masaaki;Sugie, Hajime;Tamaki, Yoshio. And the article was included in Nippon Oyo Dobutsu Konchu Gakkaishi in 1996.COA of Formula: C14H24O2 The following contents are mentioned in the article:

The structure of the sex pheromone of the most important sugarcane pest, sugarcane shoot borer, T. schistaceana was determined to establish an integrated method of controlling this pest. The sex pheromone was extracted from the abdominal tips of virgin females. Using laboratory bioassay in a small flight tunnel, 2 active components of the sex pheromone were isolated. The major and minor components were identified as (Z)-9-dodecenyl acetate and (E)-9,11-dodecadienyl acetate, resp. The major component alone had no attractivity but a mixture of the 2 components showed strong activity in sugarcane fields. The sex pheromone of T. schistaceana was determined to be a 100:1 mixture of (Z)-9-dodecenyl acetate and (E)-9,11-dodecadienyl acetate. The synergist increasing the attractivity of the sex pheromone was (E)-7,9-decadienyl acetate. The best formulation for the sex attractant was a mixture of the 2 pheromone components and the synergist at a ratio of 1000:10:1.

Determination of double-bond position in diunsaturated compounds by mass spectrometry of dimethyl disulfide derivatives was written by Vincent, Marco;Guglielmetti, Gianfranco;Cassani, Giorgio;Tonini, Cristina. And the article was included in Analytical Chemistry in 1987.Related Products of 50767-78-7 The following contents are mentioned in the article:

A method for determining the double-bond location in 24 diunsatd. compounds was examined The diene system is reacted with Me₂S₂ and a stoichiometric amount of iodine in CS₂ (or without solvent). The derivatization leads to either linear or cyclic polythioethers, depending on the number of CH₂ groups separating the 2 double bonds. The mass spectra of the derivatization products show fragmentation which is strongly influenced by the sulfurated groups introduced, so that the original position of the double bonds is easily deduced. Only conjugated dienes give derivatives with scarcely meaningful mass spectra. The derivatization has a moderate anti stereoselectivity when cyclic polythioethers are obtained, since several diastereomers can be distinguished by gas chromatog. No conclusive statement is possible about the stereochem. of the derivatization leading to linear polythioethers, where a different reaction mechanism is observed This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Related Products of 50767-78-7).
