## Abstract Methyl __cis__,__cis__‐, __trans__,__cis__‐, __cis__,__trans__‐, and __trans__,__trans__‐12,15‐octadecadienoates‐9,10‐d~2~ were prepared by the Wittig Reaction between __cis__‐ or __trans__‐3‐hexenyltriphenylphosphonium bromide and methyl 12‐oxododecanoate‐9,10‐d~2~ with butyl lithium i
## Abstract The proton NMR spectra of four __cis__/__trans__ pairs of 1,2‐disubstituted olefins have been analysed. The observed trends of the olefinic, vicinal and allylic proton‐proton coupling constants are discussed in terms of rehybridization at the __sp__^2^ carbon atoms. It is found that in
