Aerobic Oxidation of Cyclohexane Catalyzed by Flame-Made Nano-Structured Co/SiO2 Materials

Equivalent-Continuum Modeling of Nano-Structured Materials

A method has been proposed for developing structure-property relationships of nano-structured materials. This method serves as a link between computational chemistry and solid mechanics by substituting discrete molecular structures with equivalent-continuum models. It has been shown that this substitution may be accomplished by equating the molecular potential energy of a nano-structured materi...

Mechanistic 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).

Novel Polyaniline Supported Cobalt Catalyzed Aerobic Oxidation of Alkenes

Mechanism 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...

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.
