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).
(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. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Related Products of 50767-78-7
