ABSTRACT:
A new process for preparing 1,2-disubstituted-trans-olefins selectively by reacting specific 2-alkenyl phosphonic acid derivatives with metal hydrides, and a new process for producing the specific 2-alkenylphosphonic acid derivatives. The 1,2-disubstituted-trans-olefins are useful as precursors for synthesis of insect pheromones.
