The photochemical reaction of perfluoroalkyl iodide with α-methylstyrene and related compounds in the presence of hexabutylditin under oxygen atmosphere produces the fluoroalkylated alcohols in good yields. The reaction was photochemically initiated, and proceeded via a radical chain mediated by the ditin.
A convenient method for the one-pot synthesis of heterocyclic compounds bearing a perfluoroalkyl group from α-chlorostyrenes via perfluoroalkylated α,β-unsaturated ketones has been developed.
