(Z)-Hexadenes, their epoxides and arylanalogs were prepared s'tereo-specifically by Wittig reaction of alkylidenetriphenylphosphoranes with alkylaldehydes or arylaldehydes respectively.(E)-5-Hexadecene was obtained from the conversion of (Z)-5-hexadecene via addition of bromine, elimination-reduction with NaNH₂/NH₃ These compounds are active in EAGresponses.
