New Approaches toward Building Csp -P bond: A Two-Decade Overview

Abstract

Since the review of Savignac, the past 20 years have seen significant progresses on the synthesis of alkynylphosphorus compounds considerably expanding the original and rather limited organic toolbox. This comprehensive review explores the latest and potentially greener methodologies using sustainable catalysis or direct metal-free couplings from stable and easy to handle precursors. Recent progress and mechanistic insights for metal-catalyzed reactions with a particular emphasis on copper, palladium, nickel and silver catalytic systems, photocatalytic and metal-free reactions are detailed covering most of the publications related to this field since 2000 until March 2022.

Keywords: Csp−P bond formation; alkyne; alkynyl phosphorus compounds; metal-free reactions; transition-metal-catalyzed reactions.
