Insertion of a Copper Nitrene into a C-H Bond to Form Bis(2-(Phenylamino)-1,10-phenanthrolinato)dicopper(I): A Short Cu-Cu Distance with No Bond

摘要

Since 1967, several transition-metal tetrazene complexes have been reported,including derivatives of Ni, Pt, Co, Rh, Ir, and Fe. We recently prepared several transition-metal tetrazene complexes from the readily available tetrazenido dianion. This reagent has permitted the synthesis of tetrazene bonding within a triad. This reagent has also been applied to the preparation of main-group tetrazene compounds and the first early-transition-metal tetraazabutadienes. The results of the above studies prompted us to investigate the possibility of forming a Cu-tetrazene complex with I, since they are unknown for this metal. Herein we report the unexpected results from the reactions between I and a dihalo Cu(II) complex.
