Reactions of benzil mono- and bis-arylhydrazones
Abstract
A number of benzil and anisil mono- and bis-arylhydrazones were prepared. The behaviour of the monohydrazones indicated their existence in a chelated form (I). The bisarylhydrazones were acetylated and also cyclised to 2,4,5-triaryl-1,2,3-triazoles (III), whose bromination was studied. The u.v. and i.r. absorption data of the compounds prepared are given.
