We report the formation of dinuclear complexes from, and photochemical oxidation of, (CH3)3-Pt(IV)(N^N) (N^N = 1,2-diimine derivatives) complexes of thiophenolate ligands to the analogous sulfinates (CH3)3Pt(N^N)(SO2Ph) and structural, spectroscopic, and

Direct fluorination of ortho-, meta- and para-substituted aromatic thiols and disulfides using elemental fluorine afforded substituted (pentafluorosulfanyl)benzenes. This work thus represents the first study of the scope and limitation of direct fluorination for the synthesis of new SF5-containing building blocks. Fluorinations in batch and flow modes were compared. A comprehensive computational study was carried out employing density functional and wave function methods to elucidate the reaction mechanism of the transformation of ArSF3 into ArSF5. Eliminating various nonradical pathways, it has been shown that the reaction proceeds by a radical mechanism, initiated by the attack of the F. on the ArSF3 moiety, propagated via an almost barrierless F2+ArSF4 .→ArSF5+F. step and terminated by the ArSF4 .+F.→ArSF5. Most of the calculated data are in very good agreement with experimental observations concerning the ortho-substituent effect on the reaction rates and yields.

Herein the synthesis of various SCF218F-containing derivatives is reported by a transition metal-free process. By using HCF218F, readily generated from a bench-stable difluoromethyl sulfonium salt, various aromatic disulfides were easily converted into the desired radiolabelled trifluoromethylthiolated compounds in the presence of a base. This protocol allowed the formation of the SCF218F-containing aromatic derivatives in good to excellent radiochemical yields. This process was also extended to the corresponding selenium derivative.
