Abstract

Diphenyldiazomethane effects a two-electron oxidation of the uranium(IV) monoimido complex (C5Me5)2U(=N-2,4,6-t-Bu3C6H2) to give the uranium(VI) mixed bis(imido) complex, (C5Me5)2U(=N-2,4,6-t-Bu3C6H2)(=N-N=CPh2), which undergoes a rare cyclometallation reaction upon mild thermolysis to afford a uranium(IV) bis(amide) complex that results from net addition of a C-H bond of an ortho tert-butyl group across the N=U=N core.
