摘要：

A solution of the dimeric [Pt2Cl4(C2H4)2] in ethanol has been shown to contain predominantly the monomeric species trans-Pt(C2H4)Cl2(C2H5OH). Spectrophotometric studies have yielded for the reaction: Pt(C2H4)Cl3- + C2H5OH ⇄ Pt-(C2H4)Cl2(C2H6OH) + CI-, K = 5 × 10-6 M at 25°. The isotopie exchange of the chlorides cis to C2H4 occurs according to a rate expression: ReK = kd[Pt(C2H4)Cl3-] [Pt(C2H4)Cl2(C2H5OH)], where kd = 7.7 × 10-2 M-1 sec-1 for 25°, and ΔH≠ = 25 kcal/mol and ΔS≠ = 19 cal/deg mol. A possible mechanism for this process is discussed. © 1968, American Chemical Society. All rights reserved.
