A free-radical addition reaction, the solvent-dependence of which has been studied in thirty-nine solvents, is the addition of the 4-(dimethylamino)benzenethiyl radical to a-methylstyrene cf. Eq. (5-72) [576]. 

An extensive survey article on thiyl radicals has recently appeared in Patai s series. Absolute rate constants for the addition of par jf-substituted benzenethiyl radicals to monosubstituted acetylenes has been determined by a flash photolysis technique (Scheme 2)29.30,30a is a large spread in the reactivities (rate constants vary by 4 orders... 

An alternative method to the commonly used [3+2] cycloaddition reaction was reported by Oshima and coworkers, where they demonstrated the synthesis of cyclopentane derivatives via a radical mediated cyclization [45]. This was achieved through the generation of a benzenethiyl radical, which subsequentiy led to the formation of substituted cyclopentanes via ring-opening of the vinyl-substituted cyclopro-panediester, followed by the addition of electron-rich and electron-poor olefins (Scheme 10.53 and Table 10.19).
