INNER COORDINATION SPHERE TIN(IV) COMPLEXES WITH SOME O,N,N-TERDENTATE N-(2-HYDROXYBENZALDEHYDE)-1-AMINO-2-PHENYLENEIMINE AND YDROXY-1-NAPHTHALDEHYDE)-1-AMINO-2-PHENYLENEIMINE) AND O,N,N,O-QUADRIDENTATE N'-BIS(2-HYDROXYBENZALDEHYDE)-1,2-PHENYLENEDIIMINE AND (2-HYDROXY-1-NAPHTHALDEHYDE)-1,2-PHENYLENEDIIMINE) SCHIFF-BASES

From the reactions of SnCl4 with organotin(IV) chlorides (RSnCl3, R2Sn Cl2 and R3SnCl, where R = Bu, Me and Ph) with -(2-hydroxybenzaldehyde) -1-amino-2-phenyleneimine, ydroxy-1-naphthaldehyde)-1-amino-2-phenylen eimine, N'-bis(2-hydioxybenzaldehyde)-1,2-phenylemediimine and s(2-hyd roxy-1-naphthaldehyde)-1,2-phenylenediimine a series of complexes have been synthesized and characterized, respectively, by microanalytical, IR and H-1 NMR spectroscopic methods. The Ph2SnCl2 reacted with hydro xy-1-naphthaldehyde)-1-amino-2-phenyleneimine giving Ph2Sn(NAPPDI) [wh ere NAPPDI = deprotonated 2-hydroxy-1-naphthaldehyde)-1,2-phenylenedii mine], wherein the former Schiff base exhibit a facile intramolecular C=N bond cleavage and intermolecular C=N bond formation.
