The free-radical addition of phenyl trichloromethyl selenide to alkenes: A new method for the regioselective carboxylation of alkenes

Back, Thomas G.,Minksztym, Kazimierz

, p. 1759 - 1760 (1997)

The free-radical addition of phenyl trichloromethyl selenide to alkenes affords 2-phenylseleno-1-trichloromethylalkanes, which can be converted into α,β-unsaturated carboxylic acids or amides by base-promoted dehydrochlorination, followed by [2,3]sigmatropic rearrangement of the corresponding selenoxides in the presence of water or diethylamine, respectively.
