Abstract: Schiff base transition metal complexes [M(L2)X2] ¬(C1-C4), [M(L)(PPh3)2X2] (C5-C8) and [M(L)(Phen)X2] (C9-C12) where M= Co (II), Ni(II), Cu(II) and Zn(II), X= Cl, L= 2-Phenyl 3-benzylamino, 1,2 -dihydroquinazolin-4(3H)-one (PBADQ) were synthesized. All these complexes were characterized by IR, 1H NMR, 13C NMR, TGA, BET, ESR and XRD analysis. These complexes were screened for C3-Benzylation of indole and synthesis of Bis (indolyl) methanes. It is observed that all the complexes worked as the efficient catalysts. Especially mixed ligand transition metal complexes with triphenylphosphine and 1, 10-Phenanthroline ligands show greater activity as compared to other Schiff base complexes.
