Optimal conditions for distannoxane catalyzed transesterification of methyl esters with benzylic alcohols were established by studying the polycondensation of hex‐3‐ene‐1, 6‐bis(methyl oate) ( 1 ) with 1, 4‐bis(hydroxymethyl)benzene ( 2 ). α, ω‐Dicarbomethoxy‐1, 4‐oligobutadiene ( 3 ) was obtained by cross metathesis between cycloocta‐1, 5‐diene and 1. The synthesis of 1, 4‐bis[4‐(hydroxymethyl)cinnamoyl]‐benzene ( 4 ) were conducted starting from 4‐(diethoxymethyl)benzaldehyde ( 5 ) and 1, 4‐diacetylbenzene. Finally the organosoluble polyester ( PE3/4 ) were synthesized by reacting 3 with 4 and the occurrence of crosslinkings by UV irradiation was checked.
