Abstract

Diphenyldiazomethane effects a two-electron oxidation of the uranium(IV) monoimido complex (C5Me5)2U([double bond, length as m-dash]N-2,4,6-t-Bu3C6H2) to give the uranium(VI) mixed bis(imido) complex, (C5Me5)2U([double bond, length as m-dash]N-2,4,6-t-Bu3C6H2)([double bond, length as m-dash]N–N[double bond, length as m-dash]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[double bond, length as m-dash]U[double bond, length as m-dash]N core.
