(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.

A stereocontrolled synthesis of Z and E terminal dienes from pinacol E-1-trimethylsilyl-1-propene-3-boronate was written by Tsai, David Jieh Shyh;Matteson, Donald S.. And the article was included in Tetrahedron Letters in 1981.Application of 50767-78-7 The following contents are mentioned in the article:

Treatment of the pinacol boronate I with RCHO [II; R = Ph, (CH2)6Me, (CH2)8OAc] followed by cleavage of the boronate, gave 3-silyl-4-hydroxy-1-alkenes, which were deoxysilylated stereoselectively to give Z– or E-1,3-dienes in â‰?8% isomeric yield. Thus, AcO(CH2)8CH(OH)CH(SiMe3)CH:CH2 (III), prepared from I and II [R = (CH2)8OAc] in 92% yield, was treated with KH in THF (10 min) followed by aqueous NaHCO3 to give 85% Z-AcO(CH2)8CH:CHCH:CH2 (Z–IV). Treatment of III with H2SO4 in THF (10 min) followed by aqueous NaHCO3 gave 88% E–IV. The sex pheromone of Disparopsis castanea is a 20/80 mixture of Z– and E–IV. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Application of 50767-78-7).
