2-phenyliminomethylphenols (I) and 2-phenylaminomethylphenols (II) are described. Acid dissociation constants, determined potentiometrically, for the amines (II) are related to substituent constants; values are not obtained for Schiff bases(I) due to their hydrolysis. IR spectra of the amines (II) indicate chelate ring formation via OH⋯N hydrogen bonding. NMR spectra for Schiff bases (I) are consistent
摘要描述了2-苯基亚氨基甲基苯酚(I)和2-苯基氨基甲基苯酚(II)的合成。电位测定的胺(II)的酸解离常数与取代基常数有关。由于席夫碱(I)的水解作用,因此无法获得这些值。胺(II)的红外光谱表明通过OH⋯N氢键形成螯合环。Schiff碱(I)的NMR光谱与酚亚胺互变异构体一致,而不与酮胺互变异构体一致。配体(I)与铜(II)形成双配合物,而胺(II)在乙酸根阴离子存在下形成铜(II)配合物;这些材料的磁测量表明在固态下没有金属与金属的相互作用。
