Abstract
A dinitrile is reacted with hydrogen in the presence of a solvent and a catalyst to form an omega-aminonitrile such as epsilon-aminocapronitrile at high selectivity. The catalyst is a rhodium complex of the formula (RR'Rh)A reacted with a strong base such as sodium hydroxide. R is derived from a diene such as 1,5-hexadiene. R' is a heterocyclic containing an aromatic ring nitrogen. A is a complex monovalent anion such as hexafluorophosphate.
