The pressure and/or temperature dependencies of the rates of substitution of thiourea in cis‐ and/or trans‐[PtBr(2, 4, 6‐Me 3 Ph)(Et 3 P) 2 ] were studied in ethanol, DMSO, and acetone. The rate constants for both the nucleophile independent and nucleophile dependent reactions were measured. The rate and activation parameters are discussed in reference to data reported earlier for these reactions in methanol.
