Abstract

The recyclable Ru/C catalyzed oxidative α-cyanation of tertiary amines with ethyl cyanoformate by using TBHP as an oxidant under ambient conditions has been developed. Utilizing this protocol, α-aminonitrile derivatives were synthesized in good to excellent yields with high selectivity. The cyanide source (ethyl cyanoformate) employed herein was relatively cheap and less toxic, which would be beneficial. The catalyst was also inexpensive and commercially available as well as recyclable up to four cycles, without significant loss of its catalytic activity.
