Acid-aided selectivity in bromination of 1-aminoanthraquinones
Chamberlin
, p. 27 - 31 (2007/10/02)
Selectivity in the bromination of 1-aminoanthraquinones was studied. The addition of mineral acids was surprisingly found to enhance selectivity for the four isomer and consequently give an enhanced yield.
