The reaction of aromatic chlorides, bromides and iodides with various primary or secondary amines in a tetrahydrofuran solution under highpressure 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
在 6-12 kbar 的高压下,芳族氯化物、溴化物和碘化物与各种伯胺或仲胺在四氢呋喃溶液中反应,得到相应的仲胺和叔芳胺。产品的产率取决于所用胺的体积。与无环叔胺的低反应性相比,1,4-二氮杂双环 [2.2.2] 辛烷和奎宁环以高产率得到 N-芳基季铵卤化物。
