摘要：

The pressure and temperature dependencies of the rates of substitution of cis- and trans-[Pt(PEt3)2(2, 4, 6-Me3C6H2)Br] by iodide and thiourea have been studied in methanol. The volumes of activation are all negative, between-11 and -16 cm3 mol-1, for both the nucleophile independent (k1) and dependent (k2) paths. Values for ΔH‡ and ΔS‡ for the cis to trans isomerization process are also reported. The results are discussed with reference to recent literature data and are interpreted in terms of associative processes. © 1979, American Chemical Society. All rights reserved.
