The complex trans-[Pt(F)(SF3 )(PCy3 )2 ] (1) shows a diverse reactivity pattern at the SF3 ligand towards ethanol and Me3 SiOEt. This led by deoxyfluorination or alcoholysis to the generation of platinum complexes bearing a metal-bound S(O)F or S(OEt)2 group. For the latter reaction trans-[Pt(F){S(F)(OEt)2 }(PCy3 )2 ] is suggested as an intermediate. In reactivity studies of trans-[Pt(F)(SF2 )(PCy3 )2 ][BF4 ] the complex [Pt(F){S(F)(OEt)}(PCy3 )2 ][BF4 ] was prepared, which does not react with ethanol.
