Abstract
This account reviews some innovative (“non-classical”) synthetic strategies for the formation of CP bonds developed during the last decades. It provides examples of the most important milestones in this field, highlighting the state-of-art of functional phosphoruscontaining molecules. Among these are the direct functionalization of organic substrates through chlorine-free reactions with elemental phosphorus, syntheses based on phosphinidene (RP) transfer, phosphorylating methodology employing multiple bonds containing P(III) compounds, reactions with stable heterocyclic carbenes, and synthetic approaches using phosphaethynolate and bis(trichlorosilyl)phosphide salts.
Keywords: C-P bond forming reactions, elemental phosphorus, phosphinidene transfer, phospha-Wittig reaction, phospha-Fritsch- Buttenberg-Wiechell rearrangement, phosphaalkynes, phosphaalkenes, phosphinylidene carbenoids, phosphaethynolate anion, bis(trichlorosilyl) phosphide salts.
