The photolysis of trifluoromethanethiosulfonates (CF3SO2SR) or trifluorothi
oacetates (CF3COSR) in the presence of alkenes provides (trifluoromethyl)al
kanes or beta-sulfanyl (trifluoromethyl)alkanes. The formation of these com
pounds can be controlled by the nature and the ratio of the reactants. (C)
