slightly modified conditions. The C-S bond-forming reaction is reversible: A reaction of a thiol and a 1-alkylthio-1-alkyne in the presence of the rhodium catalyst gave a 1-alkyne; alkylthio exchange reaction proceeded between a 1-alkylthio-1-alkyne and a disulfide. This is an equilibrating oxidative reaction of organic molecules with C-H and S-S bond metathesis forming C-S and S-H bonds.

regio- and syn-selectivity is disclosed. C–S σ-bond cleavage of partially unsaturated sulfur-containing bifunctional reagents in an overall strain-release-driven process enables the thio-alkynylation, -alkenylation, and -allylation of BCBs under mild conditions and demonstrates the generality of this protocol. Mechanisticstudies suggest that the intermediacy of cyclic distonic radical cations might be
