摘要

Abstract 3, 5-Dihalo-2-aminobenzophenones 2 on prolonged reflux in dry pyridine gave 2, 4, 8, 10-tetrahalo-6, 12-diaryldibenzo [b, f][1, 5] diazocines 3 in high yields. Attempted condensation of 2 with glycine ester hydrochloride under identical reaction conditions failed to afford 1, 4-benzodiazepines.
