Abstract
Twenty-five new compounds of the form (PhCH2Me2SiCH2)3SnSP(X)(ORl)(OR2)(X = O:R1 =C2H5, R2 = Substituted phenyl; X = S:R1 = R2 = hydrocarbyl) have been synthesized. Their structures were characterized by IR, 1H, 119Sn, 31P NMR, MS and elemental analyses. 119Sn NMR measurement of chemical shift have shown that there is a good linear relationship of 119Sn chemical shift with para-substituent Hammett constants.
