摘要：

This paper describes the oxidation of Pt-II(phpy)(2) (phpy = 2-phenylpyridine) with two different electrophilic chlorinating reagents-PhICl2 and N-chlorosuccinimide (NCS). Pt-II(phpy)(2) reacts with PhICl2 to provide the Pt-IV complex (PtCl2)-Cl-IV(phpy)(2) as a mixture of symmetrical and unsymmetrical isomers. In contrast, the reaction of Pt-II(phpy)(2) with NCS affords a mixture of the Pt-III dimer [(phpy)(2)(Cl)Pt-III](2) and (PtCl2)-Cl-IV(phpy)(2), whose ratio varies as a function'of reaction time, concentration, and the presence/absence of ambient light. The implications of these results for the mechanisms of the two reactions are discussed in detail.
