Zincke studied the action of nitrous acid on the bromine derivatives of the cresols, and found that in the meta series the halogen atom para to hydroxyl is replaced by the nitro radical, while in the ortho and para series the atom ortho to hydroxyl is replaced. In no case did he report the formation of isomeric compounds as a result of a single nitration.
