Abstract

N-Substituted cyclic amines are prepared by reacting diols with primary amines over a copper-containing catalyst which is obtainable by impregnation of an inert support with an aqueous solution of an ammine complex of a readily thermally decomposable copper compound and subsequent drying and calcination and contains from 5 to 50% by weight of copper, calculated as CuO.
