The use of the new Fe3O4@Salicylic acid nanocatalyst (Fe3O4@SA) is described in the synthesis of 3, 4 dihydropyrimidin-2(1H)-ones/thiones and benzylidenemalononitrile in a solvent-free (SF) environment at 80◦C as a simple, effective, and environmentally friendly procedure. In the present protocol, we have created new, simple chemical co-precipitation method for the synthesis of efficient and magnetically recoverable […]
