  19F NMR study ofcis- andtrans- effects of substituted triphenylphosphine ligands intrans-(4-fluorophenyl)triarylphosphine-tri(4-fluorophenyl)phosphineplatinum 4-fluorothiophenoxides

  摘要：

  A number of compounds of the type of trans-4-FC6H4Pt(PAr3)(2)SC6H4F-4, where Ar is a substituted phenyl group, have been prepared starting from the corresponding chlorides. By exchange reactions of trans-4-FC6H4Pt[P(C6H4F-4)(3)]2SC6H4F-4 with the above-mentioned compounds or Ar3P, trans-4-FC6H4Pt[P(C6H4F-4)(3)][PAr3]SC6H4F-4 have been generated in solution. For the latter compounds, the effect of Ar3P on cis- and trans-ligands has been studied by the F-19 NMR technique. It has been shown that the cis- and trans-effects of Ar3P run parallel and are well described by pK(a) values and ionization potentials of the unshared electron pair in Ar3P, as well as by sigma(0) constants of the aryl groups.
