Abstract

© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. In the presence of stoichiometric or catalytic amounts of [M{N(SiMe 3 ) 2 } 2 ] (M=Fe, Co), N-heterocyclic carbenes (NHCs) react with primary phosphines to give a series of carbene phosphinidenes of the type (NHC)·PAr. The formation of (IMe 4 )·PMes (Mes=mesityl) is also catalyzed by the phosphinidene-bridged complex [(IMe 4 ) 2 Fe(μ-PMes)] 2 , which provides evidence for metal-catalyzed phosphinidene transfer. Carbene phosphinidenes of the type (NHC)·PAr (NHC=N-heterocyclic carbene) can be synthesized using a catalytic phosphinidene-transfer reaction between primary phosphines and NHCs, with the simple iron or cobalt amide, [M{N(SiMe 3 ) 2 } 2 ] (M=Fe or Co), as the catalyst.
