Carbazole/cyanobenzene photocatalysts promote the direct isotopic carboxylate exchange of C(sp) acids with labeled CO. Substrates that are not compatible with transition-metal-catalyzed degradation-reconstruction approaches or prone to thermally induced reversible decarboxylation undergo isotopic incorporation at room temperature in short reaction times. The radiolabeling of drug molecules and precursors with [C]CO is demonstrated.
咔唑/氰基苯光催化剂促进 C(sp 3 )酸与标记的 CO 的直接同位素羧酸交换。与过渡金属催化的降解-重建方法不兼容或易于热诱导可逆脱羧的底物，在短反应时间内在室温下进行同位素掺入。用 [C]CO 对药物分子和前体进行放射性标记。
