| Abstract: | Summary The platinum-platinum bonded PtR2(OAc)L1]2 complexes (R = Ph, L1 = Et2S, n-Pr2S; R =p-tolyl, L1 = Et2S), have been prepared by oxidising PrR2L1 ]2 with AgOAc or Tl(OAc)3. The sulphide ligand is replaced by weak ligands to give PtR2(OAc)L2]2 (L2 = PhNH2, 4-picoline, CI–) whereas PEt3 or P(OMe)3 react to give Pt2R4(OAc)2(PR 3)(R = Et, OMe). The methyl platinum analogues could also be prepared. Similar complexes Pt2Me4(O2CCF3)2L3 (L3 = Et2S1 4-picoline) were obtained by the reaction of Hg(O2CCF3)2 with PtMe2(O2CCF3)L3]2.31p,1H and13C n.m.r. of the complexes are reported. |
