Type: article

Abstract: The insertion of carbon disulfide into the Ru H bond of CpRu(PAr 3 ) 2 H (Ar 3 = Ph 3 , 1 , Ph 2 (p-tolyl), 2 , (p-tolyl) 3 , 3 , and (p-anisyl) 3 , 4 ) in C 6 D 6 is first order in each reactant and second order overall. The relative rate of reaction is 4 ≈ 3 > 2 > 1 suggests that a stronger σ-donor ligand increases the hydridicity of the Ru H bond and increases the rate of insertion. Activation parameters were measured for the reaction of 1 with CS 2 as ∆H † = 70 ± 1 kJ/mol and ∆S † = −25.9 ± 0.2 J/mol-K.
