摘要：

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.
