Two kinds of different spacer biquaternary ammonium salts N1,N3-dibenzyl-2-hydroxy-N1,N1,N3,N3-tetra-methylpropane-1,3-diaminium dichloride (Q1) and N1,N6-dibenzyl-N1,N1,N6,N6-tetramethylhexane-1,6-diaminium dibromide (Q2) were prepared to modify montmorillonite (MMT). Copper was loaded on the modified MMT by the impregnation reduction method to form two kinds of catalytic materials Cu-Q1-MMT and Cu-Q2-MMT. They were applied to the coupling of aryl halides and aqueous ammonia. It was found that they were high active and selective catalysts for the coupling of aryl halides with aqueous ammonia under mild conditions without inert gas protection. Compared with Cu-Q1-MMT, Cu-Q2-MMT showed a higher catalytic activity. In addition, it could be separated easily and reused for 17 consecutive runs without significant loss in catalytic activity.
