Abstract

Es wird die Herstellung des bisher nur unrein bekannten 2,2′‐Di‐hydroxyl‐amino‐diphenylsulfons (IV) als reine, haltbare Verbindung beschrieben. Daraus werden 5,6‐Dihydro‐dibenzo[1, 4,5]thiadiazepin‐ll‐dioxid (VI), dessen N, N′‐Di‐acetylderivat VIII sowie die 2‐Butyl‐Hexyl‐ und ‐Tetrahydrofurfuryl‐2,3‐dihydro‐1__H__‐dibenzo[b, f]pyrazolo[1, 2‐d] [1,4,5] thiadiazepin‐9‐dioxid‐1,3‐dione (II) synthetisiert.
