| Abstract: | In the presence of stoichiometric or catalytic amounts of M{N(SiMe3)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 (IMe4)?PMes (Mes=mesityl) is also catalyzed by the phosphinidene‐bridged complex (IMe4)2Fe(μ‐PMes)]2, which provides evidence for metal‐catalyzed phosphinidene transfer. |
