2,4-cyclohexadienones, 2,5-cyclohexadienones or mixtures of isomers, depending on the substrate being oxidized. Annulation of these cyclohexadienones with the anion of 3-cyanophthalide afforded anthraquinones in high yields.
发现在甲醇中用二乙酸苯基碘铵取代的苯酚进行氧化可得到2,4-环己二酮,2,5-环己二酮或异构体的混合物,具体取决于被氧化的底物。这些环己二酮与3-氰基邻苯二甲酸酯的阴离子环化可高产率地得到蒽醌。
