On April 2, 2009, Yi, Chae S.; Kwon, Ki-Hyeok; Lee, Do W. published an article.Category: pyridine-derivatives The title of the article was Aqueous Phase C-H Bond Oxidation Reaction of Arylalkanes Catalyzed by a Water-Soluble Cationic Ru(III) Complex [(pymox-Me2)2RuCl2]+BF4-. And the article contained the following:
The cationic complex [(pymox-Me2)RuCl2]+BF4- was found to be a highly effective catalyst for the C-H bond oxidation reaction of arylalkanes in water. For example, the treatment of ethylbenzene (1.0 mmol) with t-BuOOH (3.0 mmol) and 1.0 mol % of the Ru catalyst in water (3 mL) cleanly produced PhCOCH3 at room temperature Both a large kinetic isotope effect (kH/kD = 14) and a relatively large Hammett value (ρ = -1.1) suggest a solvent-caged oxygen rebounding mechanism via a Ru(IV)-oxo intermediate species. The experimental process involved the reaction of 2-(4,5-Dihydro-4,4-dimethyl-2-oxazolyl)pyridine(cas: 109660-12-0).Category: pyridine-derivatives
