The Reaction of SnCl2 with the Complexes cis‐PtCl2 (phosphorus ligand)2 as studied by 31P and 195Pt NMR

Abstract

AbstractThe reactions of SnCl2 with the complexes cis‐PtCl2P2, P=trialkyl and triaryl phosphines and phosphites, in CDCl3 and CD2Cl2 have been studied using 31P and 195Pt NMR. methods. For equimolar amounts of Sn and Pt, products of the type PtCl(SnCl3)P2 are formed with the complex geometry depending on the nature of P. For PPEt3 and P(OPh)3, further addition of SnCl2 produces trans‐Pt(SnCl3)2 complexes. The syntheses of trans‐PtCl(SnCl3) (PEt3)2 and trans‐Pt(SnCl3)2 (OPh3)2 are described.
