Abstract

Abstract Terminal alkynes (including acetylene) undergo regioselective hydroesterification to unsaturated cis-diesters using PdCl 2, CuCl 2, HCl, alcohol, carbon monoxide, and oxygen; cis-monoesters are formed from internal alkynes. These reactions are complete within two hours at room temperature and atmospheric pressure.
