ABSTRACT

Microwave assisted Microencapsulated-Cu(acac)2 [MC-Cu(acac)2] is found an efficient, environmentally benign catalyst for the one pot multicomponent condensation reaction of aromatic aldehyde, β-naphthol and amide to form the amidoalkyl naphthols in good yield. Additionally, the catalyst could be reused upto four times without the significant loss in yield and selectivity of the product. The notable features of this multicomponent one pot C-C and C-N bond forming reaction procedure are high conversations, economically cheap, operationally simple, and eco-friendly method.

Keywords: Microwave, MC-Cu (acac)2, Multicomponent reaction, Heterogeneous catalysis.
