A New Approach to the Synthesis of Symmetrical Bis(organylchalcogeno)acetylenes: Scope and Limitations

A new general method to prepare bis(organylchalcogeno)acetylenes R-Y-CC-Y-R (Y = S, Se, Te) by dehydrochlorination of the corresponding 1,2-bis(organylchalcogeno)chloroethylenes R-Y-CH=CCl-Y-R with tert-BuOK/tert-BuOH and/or KOH/DMSO is developed.Dechlorination of 1,2-bis(organylchalcogeno)-1,2-dichloroethylenes R-Y-CCl=CCl-Y-R (Y = S, Se, Te) with BuLi in ether or THF is effective only for sulfur derivatives.With Y = Se and alkyl substituents, substitution of the chlorine atom by a butyl group takes place giving rise to 5,6-bis(alkylseleno)dec-5-ene .With aryl substituents, an attack of the ArSe-group by the Bu-radical is observed leading to an aryl butyl selenide.In the case of the tellurium compound Ph-Te-CCl=CCl-Te-Ph, there is a competition between dechlorination to give Ph-Te-CC-Te-Ph, and substitution to produce the phenyl butyl telluride. - Keywords: bis(organylchalcogeno)acetylene; 1,2-bis(organylchalcogeno)chloroethylene; 1,2-bis(organochalcogeno)-1,2-dichloroethylene.
