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.

A light-induced redox-neutral Ni-catalyzed sp3 C–H alkylation of unactivatedalkenes with alkyl bromides possessing β-hydrogens is described herein. The method is distinguished by its simplicity, wide scope, and exquisite regio- and chemoselectivity profile, thus offering an entry point to forge sp3–sp3 architectures.
