The electrochemical carboxylation of Morita–Baylis–Hillman (MBH) acetates with CO2 is presented. The process proceeds in the absence of transition-metal catalysts and relies on the cathodic reduction of MBH acetates to generate nucleophilic anions that are able to trap low-pressure CO2. Valuable succinate derivatives are obtained (20 examples) in high yields (up to 90%) and with excellent functional
介绍了Morita–Baylis–Hillman (MBH) 乙酸盐与 CO 2的电化学羧化反应。该过程在没有过渡金属催化剂的情况下进行,并依赖于 MBH 乙酸盐的阴极还原以产生能够捕获低压 CO 2的亲核阴离子。以高产率(高达 90%)和优异的官能团耐受性获得了有价值的琥珀酸酯衍生物(20 个例子)。记录了转化的显着底物控制(电子性质)区域选择性以及基于控制实验的机械原理。
