چکیده
We report here a base free copper(I) catalyst for the selective aerobic oxidation of primary alcohols to their corresponding aldehydes and various diols lactones or lactols. In presence in situ generated Cu(I)-catalyst with 2,2′-dipyridylamine (dpa) as ligand 2,2,6,6-tetramethylpiperdine-N-oxyl (TEMPO) persistent radical, reaction proceeds under true conditions, at ambient temperature, utilizing air oxidant without added base. High catalytic activity over was achieved numerous (aliphatic, allylic, benzylic diols) different substitution patterns. The catalyst's stability is unique among reported Cu(I)-catalysts. It not moisture sensitive, capable e.g. oxidizing aliphatic benzyl water/acetonitrile solution moderate quantitative yield (> 99%) 3 h.

Highly practical copper(I)/TEMPO catalyst system for chemoselective aerobic oxidation of primary alcohols.
Aerobic oxidation reactions have been the focus of considerable attention, but their use in mainstream organic chemistry has been constrained by limitations in their synthetic scope and by practical factors, such as the use of pure O(2) as the oxidant or complex catalyst synthesis. Here, we report a new (bpy)Cu(I)/TEMPO catalyst system that enables efficient and selective aerobic oxidation of a...

متن کاملHighly efficient metal organic framework (MOF)-based copper catalysts for the base-free aerobic oxidation of various alcohols
Copper (Cu) containing metal organic frameworks (MOFs) are found to be highly efficient heterogeneous catalysts for oxidation of various alcohols. A wide range of alcohols, including alcohols containing inactive hetero-aryl and long-chain alkyl units, are selectively converted into their corresponding products. The catalytic efficiency of the Cu containing MOFs, along with the co-catalyst 2,2,6...
متن کاملAerobic Oxidation of Primary Alcohols Catalyzed by Copper Salts and Catalytically Active HydroxylBridged Trinuclear Copper Intermediate
We have developed a new protocol involving the “copper(II) chloride-cesium carbonate” system for the aerobic oxidation of primary alcohols. Cesium carbonates and the solvents such as toluene and 1,2-dichloroethane play important roles to form a catalytically active intermediate containing a m-hydroxyl-bridged trinuclear copper moiety (complex 1). From the X-ray crystal structure of complex 1, a...
