(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.Product Details of 50767-78-7

Pheromones. XXVI. Synthesis of sex attractants 7E-,9Z-dodecadienyl acetate, 9E,11-dodecadienyl acetate and 9Z,11E-tetradecadienyl acetate was written by Bestmann, Hans Juergen;Suss, J.;Vostrowsky, O.. And the article was included in Tetrahedron Letters in 1979.Product Details of 50767-78-7 The following contents are mentioned in the article:

Title compds R(CH:CH)2(CH2)nOAc [R = Et, n = 6 (I), 8; R = H, n = 8] were prepared by stereoselective Wittig reactions. E.g., I was prepared from cycloheptanone enol Me ether by ozonolysis, followed by Wittig reaction with Ph3P:CHCHO to give E-OCHCH:CH(CH2)5CO2Me. Carbonyl olefination with Ph3P+Pr Br–/NaN(SiMe3)2 gave 7E,9Z-Et(CH:CH)2(CH2)5CO2Me, which on reduction and acetylation gave I. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Product Details of 50767-78-7).
