Abstract
Liquid-phase thermal reactions of phenylacetylene with the system arene(hetarene)thioldiselenide at 110-180°C proceed through conjugate addition to the phenylacetylene triple bond of one alkylselanyl and one arene(hetarenesulfanyl groups to form 2-alkylselanyl-2-[aryl(hetaryl)sulfanyl]-1-phenylethenes and 1-alkylselanyl-2-[aryl(hetaryl)sulfanyl]-1-phenylethenes. Therewith, direct addition of thiols to phenylacetylene slows down.
