Abstract

Phosphine–gold(I) alkynyl complexes are stable compounds that can be subjected to palladium-catalyzed cross-coupling reactions. This article outlines the synthesis of such compounds and their ability to play the role as substrates in Sonogashira couplings is covered. This synthetic approach is particularly attractive when the related terminal alkynes are unstable.
