and electron-rich ones by employing Pd(II) as catalyst under aerobic conditions have been established, which lead to smooth synthesis of aryl halides (−I, Br, and Cl) through the decarboxylative functionalization of benzoic acids with readily available halogen sources CuX (X = I, Br, Cl), and easy preparation of benzonitriles from decarboxylative cyanation of aryl carboxylic acids with nontoxic and
建立了一种简单的策略,在需氧条件下,通过使用Cu(I)作为促进剂和富电子的Pd(II)作为催化剂,对缺电子的苯甲酸进行脱羧功能化的简单策略,从而导致芳基卤化物(-I)的顺利合成,Br和Cl),通过使用容易获得的卤素源CuX(X = I,Br,Cl)对苯甲酸进行脱羧功能化,以及使用无毒且低成本的K 4 Fe通过芳基羧酸的脱羧氰化反应轻松制备苄腈(CN)6第一次在氧气气氛下。
