Ei. Troyansky et al., HOMOLYTIC ADDITION OF DITHIOLS TO ALKYNES - A NEW APPROACH TO THE CONSTRUCTION OF DITHIACYCLANES AND CROWN THIOETHERS, Russian chemical bulletin, 46(7), 1997, pp. 1199-1210
A novel general approach to the construction of sulfur-containing hete
rocyclic compounds and crown thioethers based on one-pot ''assembling'
' of their molecules from alpha,omega-dithiols and alkynes via homolyt
ic cycloaddition has been developed.
