The synthesis of trans platinum-hydride coordination complexes

Abstract

PtHL2X (L = PPr3, PBu3; X = Cl, Br, I, NO2, CN, SCN) were prepared The synthesis is divided into 2 steps: preparation of trans-PtHL2Cl from cis-PtL2Cl2 by reduction with hydrazine; of trans-PtHL2X through metathesis reaction between trans-PtHL2Cl and KX (or NaX). The structure of trans-PtHL2X was characterized by IR and 1H NMR. The values of stretching vibration frequency nPt-H, chem. shift dH and coupling constant JPt-H decreased with the increase of trans effect.

Key words: CYANIDES, HALIDE, TRANSFORM, PROTON MAGNETIC RESONANCE SPECTROMETRY, PHOSPHINE, COUPLING CONSTANT, PLATINUM COMPLEX, CHEMICAL BONDS, CHEMICAL SHIFT, REDUCTION REACTION
