Abstract
Insect pheromones and pheromone precursors, containing one or more Z-alkenyl groups, are prepared by treating an alkyne with a copper complex, reducing agent, and proton donor in an organic solvent. The pheromones and pheromone precursors are prepared with high stereoselectivity and substantially no over reduction.
