Abstract
The catalytic activity of Schiff base Co(II), Ni(II), Cu(II) and Zn(II) transition metal complexes was tested for N-Acylation of heterocycles with acetyl chloride. It is observed that all the complexes worked as efficient catalysts. The structural type of complexes was studied by an Xray powder diffractogram (XRD). The mixed ligand complexes with PPh3 ligand show greater activity as compared to Phen complexes and Schiff base complexes. Especially complex [Ni(L)(PPh3)2Cl2] efficiently worked as a catalyst because of high thermal stability (TGA-DSC) and large catalytic surface area (BET).
Keywords: Schiff base, transition metal complexes, N-Acylation of heterocycles.
