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 CuI into CuII. 2-Bromo-1-methyl-imidazole was isolated as its self assembled tetranuclear CuII cluster, [Cu41-N-(N2C4H5Br)44-O)(μ-Br)6] 1 {η1-N-(N2C4H5Br) = 2-bromo-1-methyl-imidazole}.
