Metal-Free Photoinduced Halogen-Atom Transfer: A Novel Approach for Tetracoordinate Boron Compound Synthesis and One-Carbon Homologation and Amination of Styrenes.

We introduce a metal-free, mild four-component reaction system that involves vinylarenes, NHC-BH3 complexes, 4-cyanopyridine, and alkyl/aryl/alkenyl iodides, enabling the efficient synthesis of tetracoordinate boron compounds. Furthermore, we showcas…
