The reaction of aromatic chlorides, bromides and iodides with various primary or secondary amines in a tetrahydrofuran solution under high pressure of 6–12 kbar gave the corresponding secondary and tertiary aromatic amines. The yields of the products depend on the bulkiness of amines used. 1, 4-Diazabicyclo [2.2. 2] octane and quinuclidine gave N- aryl quarternary ammonium halides in high yields in contrast to the low reactivity of acyclic ...
