反式-Py(Py)/SUB_2/Cl/SUB_2/在不同溶剂中的氯交换速率取决于溶剂的性质，这种方式与溶剂和金属离子在速率决定步骤中的强烈相互作用相一致。轨道为空或可能为空的溶剂特别有效，可能是因为它与铂形成了圆周率键合。双亲性试剂是指在取代反应中可以同时给予电子和接受电子的物质。(身份验证)
The rate of chloride exchange of trans-Py(py)/sub 2/Cl/sub 2/ in a variety of solvents depends upon the properties of the solvent in a way consistent with strong interaction of the solvent and metal ion in the rate- determining step. Solvents with empty, or potentially empty, orbitals are partictularly effective probably because of pi -bonding to the platinum. The term biphilic reagent is proposed for substances wbich can simultaneously donate and accept electrons in substitution reactions. (auth)
