An ongoing challenge in trifluoromethylthiolation reactions is the use of less expensive and easily available trifluoromethylthio sources. Herein, we disclose an unprecedented usage of trifluoromethanesulfonic anhydride (Tf2O) as a radical trifluoromethylthiolating reagent. Hydrotrifluoromethylthiolation of unactivated alkenes and alkynes with Tf2O in the presence of PMePh2 and H2O under visible-light photoredox catalysis gave the addition products. The trifluoromethylthio radical (.SCF3) was first formed from Tf2O through a photoredox radical processes and deoxygenative reduction of PMePh2, and H2O serves as the H-atom donor for the hydrotrifluoromethylthiolation reaction. This reaction provides a new strategy for radical trifluoromethylthiolation.

The reaction of XeF2 with some organo-phosphorus, -arsenic and -iodine compounds is described.The products were identified by fluorine nmr spectroscopy and the conditions under which fluorine exchange occurs were briefly investigated.Organoiodine(III) difluorides are suitable for the conversion of Ph2Te to Ph2TeF2; the decomposition of RIF2 liberates IF2 and fluoroalkane.
