Selective benzylic C–H monooxygenation mediated by iodine oxides

open access: yesBeilstein Journal of Organic Chemistry, 2019
A method for the selective monooxdiation of secondary benzylic C–H bonds is described using an N-oxyl catalyst and a hypervalent iodine species as a terminal oxidant. Combinations of ammonium iodate and catalytic N-hydroxyphthalimide (NHPI) were shown to
