OSINT: The study discusses the widespread use and importance of chemical transformations that manipulate functional groups (FGs) in synthetic chemistry. While conventional FG interconversion reactions are well-studied, there is limited exploration in reactions that solely alter the position of FGs. The researchers present a novel approach using photocatalysis to translocate cyano groups (CN) in nitriles, allowing for the direct exchange between a CN and an unactivated C?H bond. This reaction demonstrates high selectivity for 1,4-CN translocation, which differs from traditional C?H functionalizations. The study also shows the transannular CN translocation of cyclic systems, providing access to valuable structures that are difficult to obtain through other methods. By leveraging the versatility of CN and the CN translocation step, the researchers demonstrate the synthesis of building blocks for bioactive molecules and unconventional C–H derivatives. Overall, this reaction offers a site-selective C–H transformation without requiring selective C–H cleavage.
