Hydrofluorocarbon 245fa: a versatile new synthon in alkyne chemistry.
The CFC replacement 1,1,1,3,3-pentafluoropropane (HFC 245 fa) has been established as a convenient source of trifluoropropynyllithium under mild conditions; a range of novel and known trifluoropropynyl-containing systems has been prepared in a one-pot procedure.
