Abstract
Process for the preparation of 2-phenyl-benzazoles containing as substituents at least one branched alkyl group, characterized by the fact that, by heating and/or treatment with water-splitting agents, acyl compound water is split by a some are derived from benzenecarboxylic acids and, on the other hand, from O-aminooxybenzenes, O-aminomercaprobenzenes or O-diaminobenzenes having one primary amino group and the other amino group at the most secuandary, and which contain as substituents at least one alkyl group. Branched, or by the fact that they are treated, with reducing agents that split water, acyl compounds that on the one hand are derived from benzenecarboxylic acids and on the other hand O-nitrooxybenzenes, O-nitromercaptobenzenes or O-nitroaminobenzenes with amino group the secondary sumo.
