| Abstract: | 2,3-Dichloroprop-1-ene reacted with diphenyl disulfide in the system hydrazine hydrate-potassium hydroxide at 30–35°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 60°C goes further to afford (Z)-1,2-bis(phenylsulfanyl)prop-1-ene. |
