Abstract

Radical addition of 2-substituted ethanethiols 1-5 to alkyl-, dialkyl-, and phenylacetylenes affords the corresponding β-sulfanylalkenyl radicals, which can undergo 1, 5-radical translocation (RT reaction) in competition with intermolecular hydrogen abstraction (HA reaction). The RT reaction is the first step of a sequential radical process leading to alkenesulfanyl radicals through an “intermolecular sulfanyl radical transaddition” from an ...
