functionalities and valuable building blocks commonly utilized in organic synthesis. Their cross-coupling for the synthesis of useful isolable ketenimines remains an unsolved challenge in synthetic chemistry. Herein, we report a general method for the preparation of ketenimines via a palladium-catalyzed cross-coupling of easily accessible diazo compounds with isocyanides. The reaction benefits from the
provides an efficient method for the synthesis of organometallic complexes with the 1-azaallyl ligands. It is found that an excess of ketenimine does not affect the nature of the final complexes, with only a monoinsertion product being observed. All these complexes are characterized by elemental analysis and spectroscopic properties. The structures of these complexes have also been determined through
