The research findings were recently published in the Journal of the American Chemical Society.

The generation of alkyl radicals was achieved by direct visible-light excitation of the organoborate complex, which was designed and synthesized from “boracene,” which has a boron atom in the tetracene-like skeleton. The alkyl radicals thus obtained could be used as a carbon source for chemical reactions, enabling the synthesis of complicated/bulky organic compounds. The present study offers a new protocol for organic synthesis, which is expected to accelerate e.g. drug discovery.
