SYNTHESIS OF NEW TIN(IV) COMPOUNDS OF SUBSTITUTED DIPHENYLSULFIDE DERIVATIVES AND THEIR COMPLEXES WITH SOME NEUTRAL LIGANDS

Abstract

Some new tin(IV) compounds of the general formula Sn(SC6H4R)4, where R = o-NH2, p-Me, p-Bu-t have been obtained from the direct reaction of (RC6H5S)2 and tin metal in the molar ratio 2:1 in refluxing toluene. Similarly, a mixture of tin (RC6H5S)2 and iodine in 1.0:1.5:0.5 or 1.0:1.0:1.0 molar ratios in refluxing toluene leads to the formation of Sn(SC6H4R)3I or Sn(SC6H4R)2I2 respectively. Complexes of the new tin compounds with triphenylphosphine, 4-picoline, 1,10-phenanthroline and 2,2′-bipyridine have been synthesized by the direct reaction between the tin compound and the neutral ligand. The tin compounds and their adducts have been characterized physio-chemically and spectroscopically.
