Bromination of 2,7-dinitro-9,10-phenanthrenequinone, 2,5-dinitro-9,10-phenanthrenequinone, and 2,4,7-trinitrofluorenone with bromine in concentrated sulfuric acid in the presence of acetic acid gave, respectively, 4-bromo-2,7-dinitro-9,10-phenanthrenequinone, 2-bromo-4,7-dinitro-9,10-phenanthrenequinone, and 5-bromo-2,4,7-trinitrofluorenone. No bromination occurred in the absence of nitric acid. The
在乙酸存在下,在浓硫酸中用溴溴化2,7-二硝基-9,10-菲醌,2,5-二硝基-9,10-菲醌和2,4,7-三硝基芴酮。 4-溴-2,7-二硝基-9,10-菲醌,2-溴-4,7-二硝基-9,10-菲醌和5-溴-2,4,7-三硝基芴酮。在不存在硝酸的情况下,未发生溴化反应。相同的溴化多硝基化合物可在类似条件下直接从未取代的9,10-菲醌和芴酮获得。
