Thiophenol reacts with 3-phenylthio- and 3-bromo-1-alkyne in the presence of radical initiator to give 1,2-bis(phenylthio)-1-alkene and 2-bromo-1-phenylthio-1-alkene.

A new scheme of the domino reactions of diphenyl dichalcogenides with 2,3-dichloroprop-1-ene in the system hydrazine hydrate—KOH was suggested, which included nucleophilic substitution of the allylic chlorine atom in dichloropropene, dehydrochlorination of the product obtained with the formation of an allene derivative, addition of a nucleophile to the allene system, allene-acetylene rearrangement

2,3-Dichloroprop-1-ene reacted with diphenyl disulfide in the system hydrazine hydrate-potassium hydroxide at 30-35A degrees C to give three products: 2-chloro-3-phenylsulfanylprop-1-ene, 1-phenylsulfanylpropadiene, and 1-phenylsulfanylprop-1-yne. Variation of temperature ensures selective synthesis of one of the above products, which confirms their successive formation (domino reaction). The domino reaction at 60A degrees C goes further to afford (Z)-1,2-bis(phenylsulfanyl)prop-1-ene.
