Fluorination Reactions at a Platinum Carbene Complex: Reaction Routes to SF , S(=O)F and Fluorido Complexes.

The electron-rich Pt complex [Pt(IMes) ] (IMes: [1,3-bis(2,4,6-trimethylphenyl)-2-imidazolinylidine]) can be used as precursor for the syntheses of a variety of fluorido ligand containing compounds. The sulfur fluoride SF undergoes a rapid oxidative addition at Pt to yield trans-[Pt(F)(SF )(IMes) ]. A photolytic reaction of SF at [Pt(IMes) ] in the presence of IMes gave the fluorido complexes trans-[Pt(F) (IMes) ] and trans-[Pt(F)(SF )(IMes) ] along with trans-[Pt(F)(SOF)(IMes) ] and trans-[Pt(F)(IMes')(IMes)] (IMes': cyclometalated IMes ligand), the latter being products produced by reaction with adventitious water.

Reactivity of Binary and Ternary Sulfur Halides towards Transition-Metal Compounds.

Binary sulfur fluorides exhibit an interesting reactivity towards transition metal complexes. They open up routes for the generation of sulfur-containing building blocks. Often ligands with particular properties can be constructed.
