Hydride-Transfer Reaction to a Mononuclear Manganese(III) Iodosylarene Complex.

Metal iodosylarene species have received interest because of their potential oxidative power as a catalyst. We present the first example of hydride-transfer reactions to a mononuclear manganese(III) iodosylbenzene complex, [Mn(TBDAP)(OIPh)(OH)] (; TBDAP = ,-di--butyl-2,11-diaza[3.3](2,6)pyridinophane), with dihydronicotinamide adenine dinucleotide (NADH) analogues. Kinetic studies show that hydride-transfer from the NADH analogues to occurs via a proton-coupled electron transfer, followed by a rapid electron transfer.
