Preparation of Anhydrous M(OOCCHBr₂)₂ (M = Co, Ni, Zn, Cd AND Hg) and (CH₃)₂Sn(OOCCHBr₂)₂ by the Reactions of Metal(II) Acetates and Dimethyltin(IV) Oxide with Dibromoacetic Anhydride

Abstract

Anhydrous cobalt(II), nickel(II), zinc(II), cadmium(II), mercury(II) and dimethyltin(IV) dibromoacetates have been prepared by reacting dibromoacetic anhydride with the respective metal(II) acetates or dimethyltin(IV) oxide in CCl₄. These new compounds M(OOCCHBr₂)₂ [M = Co, Ni, Zn, Cd or Hg] and (CH₃)₂Sn(OOCCHBr₂)₂ have been characterised by elemental analyses, IR, NMR (¹H, ¹¹⁹Sn), diffused reflectance spectroscopy, and magnetic susceptibility studies.
