Abstract: | A kinetic study of the reaction of M(C10H12 · OCH3)(P)]+ complexes (M = Pd, Pt; PP = 1,2-bisdiphenylphosphinoethane; C10H12 = endo-dicyclopentadiene) with hydrogen halides, HX (X = Cl, Br) in aqueous methanol at 35° C is described. The proposed mechanism involves slow formation of the solvato species M(C10H12)(solv.)(P)]2+ followed by fast reaction with X- to give M(PP)X2. |
