o-Phenylene phosphorochloridate (IV), readily prepared from catechol in good yield, reacts rapidly and quantitatively with stoicheiometric amounts of alcohols (including tertiary alcohols) in the presence of a suitable base (triethylamine or 2,6-lutidine) and in a suitable solvent (dioxan, tetrahydrofuran, or benzene). Alkyl o-hydroxyphenyl phosphate salts (IX) were thus obtained in virtually quantitative
邻苯二甲酰氯(IV)易于从邻苯二酚以高收率制得,可在合适的碱(三乙胺或2,6-二甲基吡啶)存在下,与化学计量的醇(包括叔醇)快速定量反应溶剂(二恶烷,四氢呋喃或苯)。烷基邻-羟基苯基磷酸酯盐(IX)因此以实际上定量的产率获得,有时以纯结晶化合物形式获得。
