    • The present invention relates to a method of creating a carbon-heteroatom bond, and preferably a carbon-nitrogen bond, by reacting a leaving group-bearing unsaturated compound and a nucleophilic compound. In particular, the invention relates to the creation of a carbon-nitrogen bond, using a method involving the arylation of nitrogenous organic derivatives; the inventive method consists in creating a carbon-heteroatom bond by reacting a leaving group-bearing unsaturated compound and a nucleophilic compound introducing a heteroatom which can be substituted for the leaving group, thereby creating a carbon-heteroatom bond, in the presence of a palladium-based catalyst, optionally a ligand. The invention is characterized in that the reaction takes place in the presence of an effective quantity of a metal hydroxide or ammonium hydroxide which is associated with an alcohol-type solvent.
    • 本发明涉及通过使含离去基团的不饱和化合物与亲核性化合物反应而产生碳 - 杂原子键,优选碳 - 氮键的方法。 特别地,本发明涉及使用涉及含氮有机衍生物的芳基化的方法产生碳 - 氮键; 本发明的方法包括通过使带有离去基团的不饱和化合物和引入可被取代离去基团的杂原子的亲核化合物反应产生碳 - 杂原子键,从而在钯的存在下产生碳 - 杂原子键 的催化剂,任选的配体。 本发明的特征在于反应在有效量的与醇型溶剂相关的金属氢氧化物或氢氧化铵的存在下进行。
