Descrição geral

4-Hydroxy-TEMPO benzoate is a 4-substituted 2,2,6,6-tetramethylpiperidyl-1-oxy (TEMPO) derivative.

Aplicação

4-Hydroxy-TEMPO benzoate was employed as spin probe to investigate the mechanism of synthesis of SBA-15 and to evaluate its surface properties and pore structure by electron paramagnetic resonance spectroscopy (EPR). It was also used for the functionalization of various polydienes (polybutadiene and polyisoprene). Functionalized polydienes were analyzed by gel permeation chromatography.
Recycling catalyst in hypochlorite/bromite-nitroxide oxidizing system for conversion of alcohols to aldehydes, ketones, and carboxylic acids. It circumvents the need to use a catalytic or stoichiometric heavy metal oxidant.

TEMPO Catalyzed Oxidations

TEMPO (2,2,6,6-Tetramethylpiperidinyloxy or 2,2,6,6-Tetramethylpiperidine 1-oxyl) and its derivatives are stable nitroxy radicals used as catalysts in organic oxidation reactions. TEMPO was discovered by Lebedev and Kazarnovskii in 1960. The stable free radical nature of TEMPO is due to the presence of bulky substituent groups, which hinder the reaction of the free radical with other molecules.
