Condensation of benzoin with para-substituted anilines, (X = H, Me, Cl) gave 1,2-diphenyl-2-(arylimino)ethanol derivatives (I), which
were thermally stable up to 130 ◦C, but rearranged to 1,2-diphenyl-2-(arylimino)ethanol derivatives (II), under catalyzed effect of
phenylhydrazine, para-substituted aniline and triethylamine. The products were characterized by IR- and NMR- spectral analysis.
Key words: benzoin Schiff base, phenylhydrazine, para-substituted aniline and triethylamine
