摘要

我们证明了：1）可检测到的卤素键对于从二芳基碘鎓盐中产生光驱动自由基并不重要；2）通过这种途径产生的自由基可被过渡金属捕获，用于 C-H 芳基化反应。这些研究成果是开发无需外源光催化剂的新型金属催化芳基自由基偶联反应的第一步。

Exogenous photocatalyst-free aryl radical generation from diaryliodonium salts and use in metal-catalyzed C–H arylation†

We demonstrate (1) detectable halogen bonding is not critical for enabling light-driven radical generation from diaryliodonium salts and (2) radicals generated by this route can be captured by transition-metals for C–H arylation reactions. These results are the first step toward developing new metal-catalyzed aryl radical couplings without exogenous photocatalysts.
