mechanism for the copper-catalyzed amination of diorganozincreagents by O-benzoyl-N,N-dialkylhydroxylamines is supported by following stereochemically defined organometallics through the reaction and by employing the endocyclic restriction test. A copper-catalyzed electrophilic amination of organomagnesium compounds is also described in which the use of zinc halides has been eliminated.

Synthesis of secondary and tertiaryamines has been efficiently realized from the N-alkylation of amines with alcohols by means of heterogeneous bimetallic Pt-Sn/γ-Al2O3 catalyst (0.5 wt % Pt, molar ratio Pt:Sn = 1:3) through a borrowing hydrogen strategy. The Pt-Sn/γ-Al2O3 catalyst has exhibited very high catalytic activity towards a wide range of amines and alcohols, and can be conveniently recycled
