Mechanism and Regioselectivity of the Osmium-Catalyzed Aminohydroxylation of Olefins
, 2016 The mechanism and regioselectivity of the osmium-catalyzed aminohydroxylation of olefins was investigated in detail by density functional theory (B3LYP/6-31G(d)) calculations in the gas phase and with the CPCM-solvent model. A systematic variation of the
