Abstract

Abstract 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 same ...
