synthesis of alkenes is highly significant due to their extensive applications in both synthetic and polymer industries. A transition metal-free approach has been devised for the chemoselective olefination of carboxylic acid salts. This modular approach provides direct access to valuable electron-deficient styrenes in moderate to good yields. Detailed mechanistic studies suggest anionic decarboxylation is followed
由于烯烃在合成和聚合物工业中的广泛应用,具有成本效益和高效的合成烯烃具有非常重要的意义。已经设计了一种无过渡
金属的方法用于
羧酸盐的
化学选择性烯化。这种模块化方法可以以中等至良好的产率直接获得有价值的缺电子
苯乙烯。详细的机理研究表明阴离子脱羧之后是卤素离子转移。这种卤素转移导致反应物电子的反极化,从而实现限速反弹消除。
