Direct Conversion of Arylamines to Pinacol Boronates: A Metal‐Free Borylation Process

Leave the metal out: Arylboronates are produced in moderate to good yields by direct borylation of readily available aryl amines (see scheme). The reaction can be carried out under air at room temperature and transition-metal catalysis is not required. The boronate products can be used without purification in Suzuki–Miyaura cross-coupling reactions. Detailed facts of importance to specialist readers are published as "Supporting Information".
