1,4,7-trifluoro-2-acetamidofluorene, and 5,8-difluoro-2-acetamidofluorene, of a 1,2,3,4,7-penta-, a 1,2,3,4-tetra-, a 1,2,4,7-tetra-, a 1,4,7-tri-, and a 1,4-di-fluorofluorenone, and of related derivatives is reported together with their infrared absorption data. Nitration of polyfluorofluorenones which have an unsubstituted 2 (or 7) position occurs at that position. An unexpected directive effect
5,6,7,8-四氟-2-乙酰氨基芴、1,4,7-三氟-2-乙酰氨基芴和 5,8-二氟-2-乙酰氨基芴的合成,1,2,3,4, 7-五-、1,2,3,4-四-、1,2,4,7-四-、1,4,7-三-和1,4-二-氟芴酮,和相关衍生物的数量与它们的红外吸收数据一起报告。具有未取代的 2(或 7)位的多氟芴酮的硝化发生在该位置。在 4,7-二氟-2-乙酰氨基芴的硝化反应中观察到了意想不到的指示效果。
