【 摘 要 】

A novel and practically useful protocol has been designed wherein, polyvinyl pyrrolidone (PVP) stabilized nickel nanoparticles have been used as a catalyst for promoting the synthesis of 2,2'-aryl-methylene bis(3-hydroxy-5,5-dimethyl-2-cyclohexene-1-one), 2,2'-aryl-methylene bis(3-hydroxy-2-cyclohexene-1-one), also known as tetraketones, and biscoumarins via Knoevenagel condensation followed by rapid Michael addition.
