Selective aerobic oxidation of amines to imines by TiO2 photocatalysis in water.
نویسندگان
چکیده
Selective oxidation of benzylic amines to imines with atmospheric O2 is achieved in water on TiO2 under UV irradiation. The afforded imine could be easily separated and TiO2 can be recycled by filtration. To scale up, gram-scale imine products can be obtained.

The selective oxidation of alcohols into carbonyl compounds using dioxygen in lieu of toxic or corrosive stoichiometric oxidants such as ClO , Cr, and Cl2, is one of the most challenging functional group transformations. The oxidation of alcohols using dioxygen as the oxidant has been successfully realized by using noble-metal and transitionmetal complexes for catalysis. TiO2 photocatalysis has...
متن کاملChemoselective organocatalytic aerobic oxidation of primary amines to secondary imines.
Biomimetic aerobic oxidation of primary benzylic amines has been achieved by using a quinone catalyst. Excellent selectivity is observed for primary, unbranched benzylic amines relative to secondary/tertiary amines, branched benzylic amines, and aliphatic amines. The exquisite selectivity for benzylic amines enables oxidative self-sorting within dynamic mixtures of amines and imines to afford h...
متن کاملVisible light induced green transformation of primary amines to imines using a silicate supported anatase photocatalyst.
Catalytic oxidation of amine to imine is of intense present interest since imines are important intermediates for the synthesis of fine chemicals, pharmaceuticals, and agricultural chemicals. However, considerable efforts have been made to develop efficient methods for the oxidation of secondary amines to imines, while little attention has until recently been given to the oxidation of primary a...
متن کاملOne-pot synthesis of imines from alcohols and amines with TiO2 loading Pt nanoparticles under UV irradiation.
TiO(2) loading Pt nanoparticles (Pt@TiO(2)) promote one-pot synthesis of imines from alcohols and amines under UV irradiation at room temperature. This is achieved via a Pt-assisted photocatalytic oxidation of alcohols and a catalytic condensation of the formed aldehydes with amines on the TiO(2) surface.
