Visible light-induced selective hydrobromodifluoromethylation of alkenes with dibromodifluoromethane†
Abstract
A visible light-induced selective hydrobromodifluoromethylation of alkenes using CF2Br2 was developed. This transformation proceeded smoothly in the presence of catalytic eosin Y at room temperature to give various hydrobromodifluoromethylated compounds with broad functional group tolerance.
