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