Hydrogen-Bonding Catalysis: Mild and Highly Chemoselective Oxidation of Sulfides

ADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 4 2009
Alessio Russo
Abstract N,N, -Bis[3,5-bis(trifluoromethyl)phenyl]thiourea, employed at only 1,mol% loading, was found to be a very effective catalyst for the oxidation of sulfides with tert -butyl hydroperoxide (TBHP), affording the sulfoxides in high yield, excellent chemoselectivity, fairly good diastereoselectivity.

Ionic liquid-H2O Resulting in a Highly Chemoselective Oxidation of Benzylic Alcohols in the Presence of Aliphatic Analogues Catalyzed by Immobilized TEMPO

CHINESE JOURNAL OF CHEMISTRY, Issue 3 2009

Abstract In ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6])-H2O, a highly chemoselective oxidation of benzylic alcohols in the presence of aliphatic ones to the corresponding hydroxyl benzyl aldehydes and ketones was allowed in high yields using N -chlorosuccinimide (NCS)/NaBr/IL-TEMPO (ionic liquid immobilized 2,2,6,6-tetramethylpiperidine-1-oxyl) as a facile and effective catalytic oxidation system. The medium, [bmim][PF6], together with the catalyst IL-TEMPO could be easily recycled for ten runs without any influence on the efficacy of the reaction in terms of yield and selectivity of the product.
