been developed using redox-active esters prepared in situ from alkyl carboxylates and N-hydroxyphthalimide tetramethyluronium hexafluorophosphate (PITU). This undivided cell one-pot method enables C–C bond formation using inexpensive, benchtop-stable reagents with isolated yields up to 95% with good functional group tolerance, which includes nitrile, ketone, ester, alkene and selectivity over other aromatic
使用由烷基羧酸盐和N-羟基邻苯二甲酰亚胺四甲基脲六氟磷酸盐(PITU)原位制备的氧化还原活性酯,开发了一种一锅式电化学镍催化的脱羧sp 2 -sp 3交叉偶联反应 。这种无分隔的单元一锅法可使用廉价的台式稳定剂实现C-C键的形成,分离出的收率高达95%,具有良好的官能团耐受性,其中包括腈,酮,酯,烯烃和对其他芳香族卤素的选择性。
