Abstract Copper-hydrides have been intensively studied for a long time due to their utilization in variety of technologically important chemical transformations. Nevertheless, poor stability the species severely hinders its isolation, storage and operation, which is worse nano-sized ones. We report here an unprecedented strategy access ultrastable copper-hydride nanoclusters (NCs), namely, usin...

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 )2 Fe(μ-PMes)]2 , which provides evidence for metal-catalyzed phosphinidene...
