Selective C–C bond establishment from plentiful carbonyl compounds, which represents a crucial route to get the value-added products, is still far from satisfying both academic and industrial needs. Here, confirmed by both experiment and theoretical calculation, we report versatile and efficient asymmetric cross-coupling between carbonyl radicals (from aldehydes) and aryl radicals (from aryl halides)
从丰富的羰基化合物中选择性建立 C-C 键是获得增值产品的关键途径,但仍远不能满足学术和工业需求。在这里,通过实验和理论计算证实,我们报告了在光照下采用多孔手性金属有机骨架(MOF)作为催化剂,羰基自由基(来自醛)和芳基自由基(来自芳基卤化物)之间的多功能和有效的不对称交叉偶联. 此外,由于 MOF 内的光吸收金属-氮簇和手性有机配体的可切换特性,这些 MOF 在催化仲胺介导的饱和醛和酮的不对称 β- 和 α-羰基芳基化方面表现良好。
