Title
(EN) METHOD FOR PREPARING SECONDARY AROMATIC AMINE
(FR) PROCÉDÉ DE PRÉPARATION D'UNE AMINE AROMATIQUE SECONDAIRE
(ZH) 二级芳香胺的制备方法
Abstract
(EN)
A method for preparing secondary aromatic amine by performing a C-N coupling reaction between palladium-catalyzed (pseudo) halogenated aromatic hydrocarbons or (pseudo) halogenated heterocyclic aromatic hydrocarbons and primary (heterocyclic) aromatic amine. An alkali for promoting the reaction is alkali metal carboxylate or alkali metal hydrocarbonate.
(FR)
L'invention concerne un procédé de préparation d'une amine aromatique secondaire par la mise en oeuvre d'une réaction de couplage C-N entre des hydrocarbures aromatiques (pseudo)halogénés catalysés par du palladium ou des hydrocarbures aromatiques hétérocycliques (pseudo)halogénés et une amine aromatique (hétérocyclique) primaire. Un alcali pour favoriser la réaction est un carboxylate de métal alcalin ou un hydrocarbonate de métal alcalin.
(ZH)
钯催化的(拟)卤代芳烃或(拟)卤代杂环芳烃与一级(杂环)芳香胺发生C-N偶联反应制备二级芳香胺的方法,用于促进反应的碱为碱金属羧酸盐或碱金属碳酸氢盐。
