Photoinduced metal-free α-C–H borylation of aliphatic amines

Gevorgyan and co-workers report a transition-metal-free photoinduced α-amino C–H borylation of aliphatic amines in this issue of Chem. An in-situ-formed photoactive boron complex serves as the reductant to convert aryl iodide to aryl radical. Both the selectivity during the hydrogen-atom transfer and the borylation efficiency are remarkable.
