Thiol mediated 5-(π-endo)ortho vinyl radical cyclizations

Article abstract of DOI:10.1080/10426500008076542

The radical reaction of benzenethiol with alkynes 1a-o carried out at 154 °C affords a mixture of thiol/alkyne adduct 3 and benzothiophene 5, deriving from vinyl radical intermediates 2 through hydrogen abstraction and 5-(π-endo)(orthocyclization onto the
