Mechanism of Copper/Azodicarboxylate-Catalyzed Aerobic Alcohol Oxidation: Evidence for Uncooperative Catalysis.
Cooperative catalysis between Cu(II) and redox-active organic cocatalysts is a key feature of important chemical and enzymatic aerobic oxidation reactions, such as alcohol oxidation mediated by Cu/TEMPO and galactose oxidase. Nearly 20 years ago, Markó and co-workers reported that azodicarboxylates, such as di-tert-butyl azodicarboxylate (DBAD), are effective redox-active cocatalysts in Cu-cata...
متن کاملMechanism of copper(I)/TEMPO-catalyzed aerobic alcohol oxidation.
Homogeneous Cu/TEMPO catalyst systems (TEMPO = 2,2,6,6-tetramethylpiperidine-N-oxyl) have emerged as some of the most versatile and practical catalysts for aerobic alcohol oxidation. Recently, we disclosed a (bpy)Cu(I)/TEMPO/NMI catalyst system (NMI = N-methylimidazole) that exhibits fast rates and high selectivities, even with unactivated aliphatic alcohols. Here, we present a mechanistic inve...
متن کاملAerobic oxidation catalysis with stable radicals.
Selective oxidation reactions are challenging when carried out on an industrial scale. Many traditional methods are undesirable from an environmental or safety point of view. There is a need to develop sustainable catalytic approaches that use molecular oxygen as the terminal oxidant. This review will discuss the use of stable radicals (primarily nitroxyl radicals) in aerobic oxidation catalysi...
متن کاملNon-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 کاملMechanistic Studies of Laccase/TEMPO Catalyzed Aerobic Oxidation of Alcohols
The reaction parameters for the Laccase/TEMPO system in the aerobic oxidation of aromatic alcohols were investigated. The optimized concentrations of laccase and alcohol were found to be 10 U/ml and 160 mM respectively. Under these conditions the use of 9 mol % TEMPO led to good conversions within 4 h. The optimum temperature for the reaction was found to be above room temperature (around 30°C).
