Curtius degradation with diphenic acid hydrazides
The Curtins degradation of diphenic acid monohydrazide and dihydrazide has been studied. Decomposition of the diazide produced in neutral solution 2,2′-diaminobiphenyl and 2,2′-diphenyleneurea. In alcoholic acid solution the diurethanes were formed. Decomposition of the monoazide-monohydrazide and o...

| Sumario: | The Curtins degradation of diphenic acid monohydrazide and dihydrazide has been studied. Decomposition of the diazide produced in neutral solution 2,2′-diaminobiphenyl and 2,2′-diphenyleneurea. In alcoholic acid solution the diurethanes were formed. Decomposition of the monoazide-monohydrazide and of the monohydrazide in neutral ethanolic-ethereal solution yielded phenanthridone; in alcoholic hydrogen chloride solution the esters of phenanthridone-N-carboxylic acid were obtained. © 1940, American Chemical Society.
