Chemistry – A European Journal, Volume 31, Issue 8, February 6, 2025.We report the discovery of a boron‐driven ortho‐arylation reaction of N‐aryl amides and ureas. This novel method enables directed borylation of a wide range of substrates, leading to the synthesis of unique compounds such as N‐doped fulminene and diagonal tetraarylbenzenediamines.
