The copper-assisted radical carbofluorination of unactivatedalkenes with fluoride ions is described. With [Cu(L3)F2]H2O (L3 = 4,4'-di(methoxycarbonyl)-2,2'-bipyridine) as the fluorine source and [Ag(DMPhen)(MeCN)]BF4 (DMPhen = 2,9-dimethyl-1,10-phenanthroline) as the chloride scavenger, the reaction of unactivatedalkenes with CCl4 in acetonitrile provided the corresponding carbofluorination products

technique by reacting molecularoxygen with butanone under visible lightirradiation. This method enables the mild oxidation of various functionalized compounds, including olefins, sulfides, phosphines, and silanes. Preliminary mechanistic experiments and theoretical calculations suggest that visible light triggers molecularoxygen to produce singlet oxygen in butanone. This singlet oxygen then reacts with
