摘要：

An overview is reported on early research done in our laboratory on Ligand substitution reactions of Pt(II) complexes. Some of the research was related to seminal work of Chatt on the subject, and one of our joint publications with him dealt with his view of the kinetic trans effect. Rate data on the reactions of trans-PtClL(PEt(3))(2) (L = alkyl, aryl, or hydride) show that these ligands have a large trans effect. Since these ligands do not pi bond, the results are explained in terms of the high polarizability of the ligands. Also described are reactions of different nucleophiles with trans-PtCl2(pyridine), and its use as a standard to estimate values of nucleophilic constants eta(Pt)(0), for substitution reactions of Pt(II) complexes. The data obtained were consistent with Pt(II) being a class b or soft metal and preferring the more polarizable ligand atoms.
