摘要

A recent paper15 (Bull. Chem. Soc. Jpn. 59, 1575/1986/) reported that the reactions of o- aminobenzoylhydrazine with benzylideneanilines lead to the formation of 1, 3, 4- benzotriazepin-5-one or 1-(o-benzylideneaminobenzoyl)-2-benzylidenehydrazines, depending on the substituents used. This is shown by the present paper to be incorrect. Depending on the proportions of the reagents, the above reactions lead to 1-(o- ...
