2-Chloro and 2,6-dichloroanilines, optionally substituted in the 3-, 5-, and/or 6-position are prepared from the corresponding anilides by selective bromination, chlorination, reduction and hydrolysis. The selectivity of the process for introducing chlorines ortho to the amino group is very high.
2-氯基和2,6-二氯基苯胺,可选地在3-、5-和/或6-位置被对应的苯酰胺通过选择性溴化、氯化、还原和水解制备而成。该过程引入氯原子到氨基的邻位的选择性非常高。
