Abstract
The present invention is a process specific for the preparation of bis- and tris- amines by the contact of silylorganoamines in the presence of palladium monoxide catalyst. The process results in near quantitative conversion of the silylorganoamines to the desired bis- and tris-amines, without the need for elevated pressures and without formation of salts of ammonia and chloride.
