Abstract
AbstractNiGa layered double oxide (Ni3Ga‐LDO) has been found to be an efficient heterogeneous catalyst for the α‐cyanation of aromatic tertiary amines using malononitrile as a low‐toxic cyanide source. Various aniline and aryltetrahydroisoquinoline derivatives were found to be tolerated by the catalytic system, and good to excellent yields for the corresponding products could be obtained. The results indicated that CN− might be produced via a oxidation‐decomposition path, and the reaction probably proceeded via a cross‐dehydrogenative coupling process. In addition, good stability and recyclability were observed for Ni3Ga‐LDO catalyst in the reaction.
