Radical fluoroalkylthiolation of aldehydes with PhSO2SRf (Rf = CF3, C2F5, CF2H or CH2F): a general protocol for the preparation of fluoroalkylthioesters

A general method for the preparation of fluoroalkylthioesters including trifluoromethylthio/pentafluoroethylthio/difluoromethylthio/monofluoromethylthio-esters from aldehydes and a corresponding fluoroalkylthiolating reagent was reported. The reactions were conducted under mild conditions and various common functional groups such as fluorine, chloride, bromide, iodide, and ester groups were compatible.
