A method of producing an o-disubstituted aromatic compound, containing: continuously conducting at least the following steps (a) to (d):
(a) a step of mono-lithiating one halogen atom of an o-dihaloaromatic compound, using a first microreactor;
(b) a step of making the thus-obtained monolithiated product to react with an electrophilic compound, using a second microreactor, to obtain a monosubstituted-monohaloaromatic compound;
(c) a step of lithiating the other halogen atom of the o-dihaloaromatic compound, using a third microreactor; and
(d) a step of making the thus-obtained lithiated product successively to react with an electrophilic compound, using a forth microreactor.
生产 o-二取代芳香化合物的方法,包括:连续进行至少以下步骤(a)至(d):
(a) 使用第一微反应器对 o-二卤代芳香化合物的一个卤原子进行单锂化步骤;
(b) 使用第二微反应器使得所得的单锂化产物与亲电性化合物发生反应,以获得单取代-单卤代芳香化合物的步骤;
(c) 使用第三微反应器对 o-二卤代芳香化合物的另一个卤原子进行锂化步骤;以及
(d) 使用第四微反应器使得所得的锂化产物依次与亲电性化合物发生反应的步骤。
