Carboxylate-assisted ruthenium-catalyzed direct alkylations of ketimines.

Lutz Ackermann1, Nora Hofmann, Rubén Vicente.   

Abstract

The mechanism of carboxylate-assisted ruthenium(II)-catalyzed direct alkylations of ketimines with unactivated alkyl halides was probed through experimental studies. The remarkable chemoselectivity of the broadly applicable catalyst also enabled direct alkylations among others on H(2)O or under solvent-free reaction conditions.
