Colloid and nanosize catalysts in organic synthesis: VII. Catalysis with copper colloid particles in Leucart-Wallach reaction.

Modification of Leucart-Wallach reaction using catalytic amounts of copper colloid particles was developed. Reductive amination of a series of cyclic ketones proceeds at 100°C under a small excess of formamide or of alkyl(aryl)ammonium formate. [ABSTRACT FROM AUTHOR]
