The photostimulated reaction of N-(2-halo-benzyl)aryl amines with t-BuOK in liquid ammonia affords fused azaheterocycles by the SRN1 mechanism. The starting materials are easily obtained by the reaction of 2-halo-benzyl chloride and aromatic amines to prepare the secondary amines. Through this approach, phenanthridine (90%), 4-phenylphenanthridine (87%), benzo[a]phenanthridine (98%), and benzo[c]phenanthridine
的光刺激反应ñ - (2-卤代-苄基)芳基胺与吨-BuOK在由S稠合氮杂杂环液氨得到RN 1机构。通过使2-卤代苄基氯与芳族胺反应以制备仲胺,可以容易地获得起始原料。通过这种方法,合成了菲啶(90%),4-苯基菲啶(87%),苯并[ a ]菲啶(98%)和苯并[ c ]菲啶(84%)。
