NITROGEN, OXYGEN BONDED HETROCYCLIC ORGANOSILICON (IV) DERIVATIVES OF A NEW SCHIFF BASE : SYNTHESIS AND SPECTRAL ASPECTS

MEDEPALLI DAVID RAJU

Some di, tri-organosilicon (IV) metal complexes of a new SNO tridentate heterocyclic Schiff base derived from the reaction of 1-amino-5-benzoyl-4-phenyl-1H-pyrimidine-2-thione with salicylaldehyde have been synthesized and characterized on the basis of elemental analyses, IR, 1H, 13C, 29Si NMR spectra, It has been found that the Schiff base behaves as a neutral tridentate SNO ligand forming chelates with 1 : 2 and 1 : 1 (metal : ligand) stoichiometry.
