A transition-metal-free synthesis of a series of primary arylamines from potassium aryltrifluoroborates and phenylboronic acids uses hydroxylamine-O-sulfonic acid as a mild, inexpensive source of nitrogen in cooperation with aqueous sodium hydroxide in acetonitrile. Both a sonication and a microwave-assisted method were developed.
