[Cp*RhCl2]2-catalyzed ortho-C–H bond amination of acetophenone o-methyloximes with primary N-chloroalkylamines: convenient synthesis of N-alkyl-2-acylanilines

Abstract

Rh(III)-catalyzed aromatic C–H amination of acetophenone o-methyloximes with primary N-chloroalkylamines was developed, and the arylamine products were obtained in up to 92% yield. The reaction probably involves rate-limiting electrophilic C–H bond cleavage (k_H/k_D = 2).
