[摘要]:A general protocol for direct transformation of unreactive C(sp(3))-H bonds to C(sp(3))-CN bonds has been developed. The C-H activation was effected by photoexcited benzophenone, and the generated carbon radical was subsequently trapped with tosyl cyanide to afford the corresponding nitrile in a highly efficient manner. The present methodology Is widely applicable to versatile starting materials and, thus, serves as a powerful tool for selective one-carbon elongation for construction of architecturally complex molecules. |
