摘要: A process for the chlorination of alkylanilines is provided allowing a highly selective chlorination in the meta-position of the aromatic ring. This is achieved by reacting a mixture comprising the alkylaniline and sulfuric acid with chlorine. This process allows a meta-chlorination with a selectivity of more than 90%.
摘要翻译: 提供烷基苯胺的氯化方法,允许在芳环的间位进行高度选择性氯化。 这是通过使包含烷基苯胺和硫酸的混合物与氯反应来实现的。 该方法允许以大于90%的选择性进行间氯化。
