Synthesis of N-triflyl aldimines catalyzed by imino-λ3-iodane

Abstract

We report a catalytic synthesis of N-triflyl aldimines from aldehydes and triflylamide using imino-λ³-iodane generated in situ from an iodosylarene precatalyst and triflylamide. In the present reaction, imino-λ³-iodane works as an acid–base cooperative catalyst to activate aldehydes and triflylamide.
