1,4-Di-o-tolyl-2,3-naphthoquinone (1), produced by lead tetra-acetate oxidation of 1,4-di-o-tolylnaphthalene-2,3-diol (7) at –30 °C is sufficiently stable to allow purification involving aqueous work-up and low temperature chromatography; it has been characterised by u.v. and i.r. spectroscopy, as the adduct (8) formed with norbornadiene, and by a comparison of its properties with those of the stable
1,4-二- ö甲苯基-2,3-萘醌(1)中,由1,4-二-铅四乙酸氧化产生ö -tolylnaphthalene -2,3-二醇(7在-30℃下)具有足够的稳定性,可以进行涉及水后处理和低温色谱的纯化;它的特征在于紫外和红外光谱,它是与降冰片二烯形成的加合物(8),以及与稳定的醌(9)的性能比较。
