実験手順

31 g (0.1 mol) of 1-[α-(4-biphenylyl)-benzyl]-imidazole and 27.9 g (0.1 mol) of α-biphenylyl-benzyl chloride are suspended in 200 ml of acetonitrile. The mixture is heated under reflux for 18 hours. The reaction mixture is then concentrated by distilling off the solvent and the residue, in 500 ml of toluene, is heated under reflux. The gel thereby formed is separated off and caused to crystallise by trituration with diisopropyl ether. 36 g (62% of theory) of 1,3-bis-[α-(-biphenylyl)-benzyl]-imidazolium chloride of melting point 150° C. (with decomposition) are obtained.
