In contrast with unactivated alkenes, the corresponding hydrotrifluoromethylation of styrene has remained challenging due to the strong propensity of styrene for oligomerization and polymerization. On the basis of our newly developed trifluoromethylation reagent, TFSP, herein we present a general method for the hydrotrifluoromethylation of styrene under photoredox catalysis. The substrate scope was

Anodic alpha-alkoxylation of sulfides was remarkably promoted in the presence of fluoride ions: When Et3N.3HF was used as a supporting electrolyte, simple alkyl phenyl sulfides and sulfides bearing weak electron-withdrawing groups underwent anodic alkoxylation via fluorosulfonium ions as key intermediates in a unique Pummerer-type mechanism with reasonable or high yields for the first time.
