Chloride based ionic liquids were used as chloride source in Meerwein reaction either in [bmin]X (bmim = 1-butyl-3methylimidazolium, X = BF4, PF6) as solvents or in solventless conditions. Satisfactory yields (49-71%) with diversely substituted diazonium salts were achieved by using 1,3-dibutylimidazoliurn chloride in the presence of a bimetallic Zn/Cu catalyst.
