Abstract

Polyfluorinated 2-arylhydrazono-3-oxocarboxylic acid esters react with o-phenylenediamine in neutral medium to give mainly the corresponding o-aminoanilides which can be converted into 1,5-benzodi-azepin-2-ones. In the reactions with ethyl 2-arylhydrazono-3-oxobutanoate and its 4,4-di- and 4,4,4-trifluoro derivatives, ethyl 2-(2-benzimidazolyl)-2-[(4-methylphenyl)hydrazono]ethanoate is also formed.
