The first Sn-119 NMR evidence for the presence of direct platinum-tin bond
in solution has been obtained for PtCl(SnCl3)(bdpp) complex (bdpp = (2S,4S)
-2,4-bis(diphenylphosphino)pentane). Various PtCl2(L-2) complexes (L-2 = he
terobidentate P-P, P-O, P-N, P-S chelating ligands) have been reacted with
tin(II)chloride resulting in the formation of the corresponding PtCl(SnCl3)
(L-2) derivatives. Tin(II)chloride has been inserted into the Pt-Cl bond tr
ans to the harder donor atom of the L-2 ligand.
