用水合肼还原cis-PtL2Cl2所得到的trans-PtHL2Cl与KX或NaX进行取代反应,合成了一系列trans-PtHL2X(L=PPr3, PBu3;X=Cl,Br,I,CN,NO2,SCN)新配合物,用IR、NMR研究了配合物中Pt-H键的伸缩振动频率、Pt-H偶合常数和质子化学位移δH与配体反位效应的关系.

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.
