Abstract

2-Mercapto-1-methyl-imidazoline (N₂C₄H₆S) is converted at room temperature into 2-bromo-1-methyl-imidazole (N₂C₄H₅Br) in presence of copper(I) bromide in acetonitrile-chloroform mixture viaextrusion of sulfur as sulfate and oxidation of Cu^I into Cu^II. 2-Bromo-1-methyl-imidazole was isolated as its self assembled tetranuclear Cu^II cluster, [Cu₄(η¹-N-(N₂C₄H₅Br)₄(μ₄-O)(μ-Br)₆] 1 {η¹-N-(N₂C₄H₅Br) = 2-bromo-1-methyl-imidazole}.
