What is it about?
The non-sensitized photofluoroalkylation of oxolane with perfluoroolefins (II) proceeds exclusively as monoalkylation to furnish the 2-fluoroalkylated oxolanes (III) as the major products. The completely regioselective introduction of a second fluoroalkyl substituent into the 5-position of oxolane is achieved by an acetone- sensitized photoaddition of the monoalkylated products (III) with perfluoroolefins.
