Abstract
The platinum(II) carboxylates, trans-Pt(O2CR)2(py)2 and Pt(O2CR)2bpy (R=C6F5, p-HC6F4, m-HC6F4, or o-HC6F4; bpy=2,2′-bipyridyl), have been prepared by reactions of trans-Pt(OH)2(py)2 or Pt(OH)2bpy with the appropriate polyfluorobenzoic acids, whilst [Pt(py)4](O2CC6F5)2 has been obtained from reaction of trans-PtCl2(py)2 with thallous pentafluorobenzoate in pyridine at room temperature. In boiling pyridine, the platinum(II) polyfluorobenzoates undergo either decarboxylation giving trans-PtR2(py)2 and PtR2bpy (R= C6F5, p-HC6F4, or m-HC6F4) complexes or substitution, giving [Pt(py)4](O2CC6F4H-o)2 and [Ptbpy(py)2](O2CC6F4H-o)2. Reactions of trans-PtX2(py)2 and PtX2bpy (X=Cl or Br) with appropriate thallous polyfluorobenzoates in boiling pyridine have yielded the complexes trans-PtR2(py)2, PtR2bpy, PtCl(R)bpy (R=C6F5, p-HC6F4, or m-HC6F4 in each case), trans-PtCl(R)(py)2 (R = C6F5 or m-HC6F4), trans-PtBr(C6F5)(py)2, and PtBr(C6F5)bpy. The complexes trans-PtR2(py)2 (R=C6F5 or p-HC6F4) have also been prepared from potassium tetrachloroplatinate(II) and the appropriate thallous polyfluorobenzoate in boiling py, and trans-Pt(C6F5)2(py)2 has been similarly obtained from cis-PtCl2(py)2 and C6F5CO2Tl. Significant decarboxylation was not observed on reaction of trans-PtCl2(py)2 or PtCl2bpy with thallous 2,3,4,5-tetrafluorobenzoate.
