Non-nanogold catalyzed aerobic oxidation of secondary amines to imines.
Bulk gold powder (approximately 10(3) nm particle size) is a highly active catalyst for the oxidative dehydrogenation of secondary amines to imines under the mild conditions of 1 atm O2 and 60-100 degrees C.
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 کاملDirect and mild palladium-catalyzed aerobic oxidative synthesis of imines from alcohols and amines under ambient conditions.
By ligand, TEMPO, and base screening, we developed a mild and green one-pot imine synthesis from alcohols and amines via a low-loading palladium-catalyzed tandem aerobic alcohol oxidation-dehydrative condensation reaction that can be readily carried out in open air at room temperature.
متن کاملSelective aerobic oxidation of amines to imines by TiO2 photocatalysis in water.
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.
متن کاملMetal-free aerobic oxidative coupling of amines to imines.
Oxidative coupling of primary amines to imines is achieved with high to moderate yields by refluxing suspensions of amines and water under one atmosphere dioxygen without any additives. Tandem acid-free aza Diels-Alder reactions for synthesis of N-alkyl-4-pyridones are also accomplished.
