Abstract

A new effective catalytic system consisting of [Cp* IrCl2] 2/K2CO3 (Cp*= pentamethylcyclopentadienyl) for the N-alkylation of primary amines with alcohols has been developed. As an example, the reaction of aniline with benzyl alcohol in the presence of [Cp* IrCl2] 2 (5.0 mol% Ir) and K2CO3 (5.0 mol%) in toluene at 110° C for 17 h gave benzylaniline in an isolated yield of 88%.
