A method for the synthesis of vinyl sulfides by the coupling of vinyl bromides with thiols using the copper(I) bromide as catalyst and l-proline as ligand was reported. The best yields were obtained in the ionic liquid [Bmim]BF4 with the retention of stereochemistry. This protocol is palladium-free, tolerates both aromatic and aliphatic thiols, possesses good selectivity between alcohol and thiol, and does not require the use of expensive or air-sensitive additives.

The vinylthiylation of halogen-containing compounds by acetylenes in the presence of sodium sulfide was realized.The effect of the ratio of ethylene chlorohydrin and sodium sulfide, the concentration of water, the order in which the initial reagents are mixed, and the reaction temperature on the yield of the vinyl sulfides was investigated.
