Chemo- and regioselective reductive transposition of allylic alcohol derivatives via iridium or rhodium catalysis

We report highly chemo-and regioselective reductive transpositions of methyl carbonates to furnish olefin products with complementary regioselectivity to that of established Pd-catalysis. These Rh-and Ir-catalysed transformations proceed under mild conditions and enable selective deoxygenation in the presence of functional groups that are susceptible to reduction by metal hydrides.
