An efficient method of copper-catalyzed 1,2-dihydroxylaminations of alkenes have been demonstrated under air conditions by using PhI(OAc)(2) as oxidant to furnish the dioxygenated products in 20-81% yields. This provided an alternative methodology to synthesis of dioxygenated products, which were easily transformed into diols under the reductive conditions. Furthermore, a free-radical addition mechanism was proposed in this transformation. (C) 2015 Elsevier Ltd. All rights reserved.
