Make it and break it! An overview of the different methodologies to synthesize nucleophilic phosphinidene complexes is presented. The emerging applicability of this class of phosphorus reagents as phosphinidene transfer agents that also posses the established reactivity of the isoelectronic metal-complexed carbenes makes them viable synthetic targets for a broad spectrum of chemical conversions.

Abstract

Syntheses, properties, and reactivities of nucleophilic phosphinidene complexes [LnM[DOUBLE BOND]P[BOND]R] are reviewed. Emphasis is placed on the electronic tuning of this emerging class of phosphorus reagents, using different ancillary ligands and coordinatively unsaturated transition-metal moieties. The difference in applicability of the established stable 18-electron and transient 16-electron phosphinidenes is addressed.
