Abstract
Diazaphospholenes have recently emerged as main-group hydride transfer catalysts. This review will briefly summarize the common structural variants of diazaphospholenes, and the properties that make them superb hydride transfer catalysts, followed by a critical examination of the various preparative routes toward diazaphospholenes. Finally, an in-depth examination of the reactivity of diazaphospholenes in contemporary catalysis, including asymmetric catalysis will be undertaken.

Abstract
A family of phosphine ligands containing a five-membered ring similar to the popular N-heterocyclic carbene ligands and an alkoxy third substituent has been developed. These alkoxydiaminophosphine ligands (ADAP) can be generated in one pot and reacted with a copper(I) source leading to the high yield isolation of complexes [(ADAP)CuX]2 (X=Cl, Br). The dinuclear nature of these compounds has been established by means of X-ray studies and DOSY experiments. A screening of the catalytic properties of these complexes toward carbene-transfer reactions from diazocompounds to C-H bonds (alkane, arene), olefins or N-H bonds, as well as in CuAAC or nitrene transfer reactions have shown a performance at least similar, if not better, than their (NHC)CuCl analogues, opening a new window in copper catalysis with these readily tunable ADAP ligands.
