Abstract
4-(N-Arylmethylideneamino)-2,6-t-butylphenols (I) were synthesized through the condensation of 4-amino-2,6-di-t-butylphenol hydrochloride and arylaldehydes, and the infrared and electronic spectra of phenols (I) were discussed. The oxidation of phenol (I) with lead dioxide gave a stable phenoxyl radical (II) in solution, and 4,4′-bis[4-(N-arylmethylideneamino)-2,6-di-t-butyl-2,5-cyclohexadien-1-one] (III) was isolated as a crystalline oxadation product, which was in equilibrium with the radical (II) in solution.
