Mechanistic Studies of Alkyl Chloride Acetoxylation by Pt-Sb Complexes.

ABSTRACT: The bis-acetate complexes (SbQ₃)Pt(OAc)₂ (1) and (SbQ₂Ph)Pt(OAc)₂ (2) (Q = 8-quinolinyl) were used to study C-Cl acetoxylation of 1,2-dichloroethane (DCE) to generate 2-chloroethyl acetate and the complexes (SbQ₃)PtCl₂ (1b) and (SbQ₂Ph)PtCl₂ (2b), respectively. The first acetoxylation step produced the intermediates (SbQ₃)Pt(Cl)(OAc) (1a) and (SbQ₂Ph)Pt(Cl)(OAc) (2a). The reaction was studied using pseudo first order kinetics (excess DCE) in order to compare the rates of reaction of 1 and 2, which revealed that k _obs = 2.44(6) × 10^-4 s^-1 for 1 and 0.51(2) × 10^-4 s^-
