Polyaniline supported CuI: An efficient catalyst for C–N bond formation by N-arylation of N(H)-heterocycles and benzyl amines with aryl halides and arylboronic acids, and aza-Michael reactions of amines with activated alkenes

Polyaniline supported CuI catalyst was prepared, characterized and effectively used in the N-arylation of N(H)-heterocycles and benzylamines with aryl halides and arylboronic acids and in aza-Michael reaction of amines with activated alkenes. The catalyst was recovered by simple filtration and reused for several cycles with consistent activity.
