Methods for the preparation of alkenes including insect pheromones are described. The methods include homologation reactions employing reagents such as 1,3-diesters, epoxides, cyanoacetates, and cyanide salts for elongation of starting materials and intermediates by one or two carbon atoms. The alkenes include insect pheromones useful in a number of agricultural applications.

(Z)-Alkenols and Their acetates have been synthesized by the Wittig reaction of (ω-hydroxyalkyl)triphenylphosphonium salts with alkanals by a convenient procedure. The geometrical purity of the products was evaluated to be no less than 95% of the (Z)-configu-ration by means of GLC with a glass capillary column coated with CHDMS.
