Bromination of 4H-cyclopenta[def] phenanthren-1-amine, -2-amine, -3-amine, or -8-amine with bromine in chloroform took place at the 2-, 1-, 8-, or 9-position, respectively. The second bromine was introduced at the 8-, 3-, 2-, or 3-position. Similar regioselectivity was observed in the system of bromine in acetic acid–48% hydrobromic acid and of hydrobromic acid in dimethyl sulfoxide. The corresponding
4H-环戊二烯[def]菲-1-胺、-2-胺、-3-胺或-8-胺与溴在氯仿中的溴化发生在2-、1-、8-或9-位, 分别。在 8-、3-、2- 或 3-位引入第二种溴。在乙酸-48% 氢溴酸中的溴和二甲基亚砜中的氢溴酸系统中观察到类似的区域选择性。相应的乙酰氨基化合物在与母体胺相同的位置被溴化。
