Abstract

The oxidative cyanation of tertiary amines by using the less-toxic ethyl cyanoformate as the cyanating agent was achieved over heterogeneous iron-exchanged molybdophosphoric acid (FeMPA) supported on a niobia catalyst under mild reaction conditions. The catalyst not only showed exceptional activity with variety of tertiary amines but also exhibited consistent activity upon reuse.
