Calcium carbide was studied as a useful solid-state reagent to incorporate acetylene unit into synthetic procedures. Atom-economic thiol-yne click reaction was successfully performed with single and double additions. Heterocyclic thiols and aliphatic dithiols reacted with acetylene generated in situ from calcium carbide to afford corresponding vinyl sulfides and bis(thiovinyl)ethers in good to high yields.

A method has been developed for the synthesis of N- and S-vinyl derivatives of heteroaromatic compounds from NH heterocycles or their thiols in the phase-transfer catalytic system ClCH2CH2Br-KOH (s)-18-crown-6-toluene. It is shown that it is possible to prepare N,S-divinyl derivatives of 3-mercaptoindole and 2-mercaptobenzimidazole.
