摘要：
A robust catalyst derived from NiCl2 center dot(DME) and acenaphthoimidazolium chloride exhibited high activity towards the challenging amination of bulky and heterocyclic aryl tosylates with secondary amines under mild reaction conditions at 2 mol% catalyst loading within 3 hours. Further, a wide range of primary amines were also successfully mono-aminated by our newly developed protocol.
