The complexes P](PPh3)L (L = py, 2,4-Me2C5H3N or 2,6-Me2C5H3N) and P]L2 [L2 = (Ph2PCH2)2 or (Ph2P)2(CH2)3] have been prepared by decarboxylation reactions between cis-PtCl2(PPh3)2 or PtCl2L2 and thallium(I) tetrafluorophthalate in boiling pyridine, or 2,4- or 2,6-dimethylpyridine. Reaction of cis-PtCl2(PPh3)2 with o-C6F4(CO2Tl)2 in pyridine at room temprature gives Pt[o-(O2C)2C6F4](PPh3)2, which undergoes
