Amino‐λ3‐iodane‐Enabled Electrophilic Amination of Arylboronic Acid Derivatives

Abstract

AbstractIn this report, we describe the use of amino‐λ3‐iodanes in the electrophilic amination of arylboronic acids and boronates. Iodine(III) reagents with transferable amino groups, including one with an NH2 group, were synthesized and used in the amination, allowing the synthesis of a wide range of primary and secondary (hetero)arylamines. Mechanistic studies by DFT calculations indicate that the reaction proceeds through an electrophilic amination process from a tetravalent borate complex with a B−N dative bond.
