Abstract
A novel process is described for the homogeneous hydrogenation of nitriles to primary amines utilizing anionic Group VIII metal hydride compositions as catalysts which contain phosphorus, arsenic or antimony organoligands. Use of these anionic catalysts allows the high yield hydrogenation of nitriles to primary amines to be conducted under mild conditions of temperature and pressure with high selectivity and eliminates the need for the presence of ammonia to suppress the formation of significant amounts of secondary and tertiary amines.
