By intramolecular application of LEUCKART's amide synthesis using isocyanato-diphenylsulphides, -diphenyloxides and -diphenylmethanes with AlCl3 in o-dichlorobenzene a method has been found which gives in very good yields 10,11-dihydro-11-oxo-dibenz[b,f]-1,4-thiazepines (VII), -oxazepines (VIII), and 5,6-Dihydro-6-oxo-dibenz[b,e]-azepines (XI), respectively.
