A series of unprecedented binaphthyl–osmium nanoparticles (OsNPs) with chiral modifiers were applied in the heterogeneous asymmetric dihydroxylation of alkenes. A remarkable size effect of the OsNPs, depending on the density of the covalent organic shells, on the reactivity and enantioselectivity of the dihydroxylation reaction was revealed. Successful recycling of the OsNPs was also demonstrated and high reaction efficiency and enantioselectivity were maintained.

Transfer of nitrogen and oxygen in asymmetric aminohydroxylation (AA) has been examined. Electronic as well as steric effect on the nature of oxidizing agent and nitrogen source affect chemo, regio and stereoselectivity in AA reaction. A three cycle mechanistic pathway has been proposed. Results have been rationalized through an addition of alkene to Os=N bond in a [2+2] cycloaddition manner.
