  Reactions of [MCl2(ppqMe2)2] (M=Pd, Pt) with I− and with CF3SO3H/I− including the synthesis and X-ray crystal structure of the palladium phosphidoxo complex [Pd2(μ-I)2{(PPh20)2H}2]

  摘要：

  The compounds [MI2(ppqMe2)2] (5: M = Pd; 6: M = Pt) have been synthesised and their thermolyses and reactions with strong acids investigated. Thermolysis of 5 in the presence of excess iodide ion caused complete decomposition of the complex whereas the corresponding reaction of 6 gave the P approximately O chelated complex [Pt(ppqMe)2] (7) in good yield. Treatment of 5 with CF3SO3H/I- facilitated the loss of the 2,5-dimethoxyphenyl substituent from each phosphine ligand and gave the iodo-bridged palladium(II) phosphidoxo complex [Pd2(mu-I)2{(PPh2O)2H}2] (8). An X-ray single crystal structural analysis of 8 is reported.

  produced the O,P-chelated hydroquinonate phosphine complex, cis-[Pt(O,P-PPh2thqH)2] 2. Reaction of 2 with hydrobromic acid afforded cis-[PtBr2(PPh2thqH)2] 3 which can be oxidised to give the quinone phosphine complex cis-[PtBr2(PPh2tq)2] 4. Unlike previously reported quinone phosphine complexes, 4 is robust and stable to hydrolysis; its reduction with excess of zinc and dilute hydrobromic acid produced
