In this paper, a novel heterogeneous complex of zinc with N,N-bis(2-hydroxyphenyl)pyridine-2,6-dicarboxamide(BHPPDAH) was synthesized. The catalyst was found to be a highly effective catalyst for the three-component coupling reactions of aldehydes, alkynes, and amines (A3 coupling) via C–H activation. The reactions could be applied to both aromatic and aliphatic aldehydes and alkynes. Nearly quantitative
