Synthesis and Reactivity of Copper and Copper Containing Magnetically Separable Catalysts

Abstract

This review endeavours to summarize the emergence of magnetically separable catalysts as a new class of catalyst for the modern developments in the synthesis and reactivity of the nano‐sized magnetically separable copper and copper containing nanomaterials exploited as potent applicant in the field of material science not only for their widespread technological applications but also to realize the fundamentals of nano‐magnetism. This review covers extensively different catalytic reactivity for carbon‐carbon and carbon‐heteroatom bond formation reactions and emphasized on recent developments in the field.

p-Toluenesulfonic acid-promoted organic transformations for the generation of molecular complexity

“…Dihydropyrimidinone and its derivatives have gained vast importance because of their presence in a huge family of natural compounds with varied biological functions. 19 An environmentally benign synthesis of 3,4-dihydropyrimidin-2-(1 H )-ones and thiones has been reported by Lal and co-workers from formylchromone, urea/thiourea and a variety of substituted acetophenones (Biginelli reaction) by applying p -TSA as a catalyst under microwave irradiation (Scheme 12). 20 In comparison to conventional heating, the current approach has produced outstanding yields.…”
