A variety of trialkylborane-induced reactions were examined for the preparation of the α-carbonyl radicals: (1) addition of alkyl radical to methyl vinyl ketone, (2) reduction of α-halo ketone, and (3) intramolecular radical addition to α,β-unsaturated carbonyl moiety.Trialkylborane reacted with α-carbonyl radicals to give boron enolates.The resulting boron enolates were efficiently trapped by carbonyl compounds to give β-hydroxy ketones in good yields.
