deuterocarboxylation with tetrabutylammonium oxalate as the carbonyl source and D2O as the deuteration agent was described. For the first time, the oxalic salt acted as both the reductant and carbonyl source through single electron transfer and subsequential homolysis of the C–C bond. The strongly reductive CO2 radical anion species in situ generated from oxalate played significant roles in realizing the global
本文描述了以草酸四丁基铵作为羰基源、D 2 O作为氘化剂进行炔烃氘代羧化的催化光氧化还原中性策略。草酸盐首次通过单电子转移和随后的 C-C 键均裂同时充当还原剂和羰基源。由草酸原位产生的强还原性CO 2自由基阴离子在实现末端和内部炔烃的整体氘羧化以高产率和氘化比获得各种四和三氘代芳基丙酸方面发挥了重要作用。
