✦ Synopsis

Radical Sequential Processes Promoted by 1,5-Radical Translocation Reaction: Formation and (3 + 2) Annulation of Alkenesulfanyl Radicals.

-Alkenylsulfanyl radicals can be generated by radical addition of 2-substituted ethanethiols such as (I) to alkynes. These species can undergo 1,5-radical translocation in competitions with intermolecular hydrogen abstraction depending on the nature of the substituents in the educts. The results are discussed in terms of an eventual formation of thiophene products. -
