Room temperature N-heterocyclic carbene manganese catalyzed selective N-alkylation of anilines with alcohols

Abstract

The first example of room temperature non-noble metal homogeneous system catalyzed selective N-alkylation of anilines with alcohols by a bis-NHC manganese complex is presented. This system was applied to a large range of alcohols and anilines, including biologically relevant motifs and challenging methanol. Experimental and computational studies suggest an outer-sphere mechanism for this NHC–Mn system.
