Interconversion of five- and seven-membered cyclic azo-compounds: a 1,3-azo-group migration studied by high-speed liquid chromotography
Abstract
The decomposition of the 3H-1,2-benzodiazepine (1) is accompanied by its faster equilbration with the isomeric 3H-indazole (4)via a 1,3-shif of the azo group; the establishment of equilibrium and the decomposition have been monitored by high-speed liquid chromatography (h.s.l.c.).
