Copper(ii) ketimides in sp³ C-H amination.

ABSTRACT: Commercially available benzophenone imine (HN[double bond, length as m-dash]CPh₂) reacts with β-diketiminato copper(ii) tert-butoxide complexes [Cu^II]-O ^t Bu to form isolable copper(ii) ketimides [Cu^II]-N[double bond, length as m-dash]CPh₂. Structural characterization of the three coordinate copper(ii) ketimide [Me₃NN]Cu-N[double bond, length as m-dash]CPh₂ reveals a short Cu-N_ketimide distance (1.700(2) Å) with a nearly linear Cu-N-C linkage (178.9(2)°). Copper(ii) ketimides [Cu^II]-N[double bond, length as m-dash]CPh₂ readily capture alkyl radicals R˙ (PhCH(˙)Me and Cy˙) to form the corresponding R-N[double bond, length as m-dash]CPh₂ products in a process
