T. Nakamura et al., Triethylborane-induced radical addition of halogenated compounds to alkenes and alkynes in water, SYNLETT, (12), 1998, pp. 1351-1352
Treatment of a mixture of alpha-iodo-gamma-butyrolactone and phenylacetylen
e in water with a-catalytic amount of triethylborane provided the correspon
ding adduct in good yield via intermolecular radical addition reaction. The
triethylborane-mediated radical reaction in aqueous media could be perform
ed under acidic or basic conditions.
