We report that an aqueous Ti(III)/t-BuOOH system promotes the efficient domino radical reaction of arylamines with alcohol cosolvents leading to beta-aminoalcohols in good yields, in less than ten minutes at room temperature. The free-radical mechanism according to which the amine reacts with two molecules of the alcohol is discussed. (C) 2010 Elsevier Ltd. All rights reserved.
