TEMPO-Based Ionic Liquid with Temperature-Dependent Property and Application for Aerobic Oxidation of Alcohols.

A novel temperature-dependent ionic liquid based on 2,2,6,6-tetramethylpiperidine-1-oxyl and polyethylene glycol 600 was developed and used in oxidation of alcohols. Various alcohols were oxidized into their corresponding aldehydes or ketones with good yield and selectivity. Owing to the temperature-dependent property of the catalyst, easy recovery was achieved by simple decantation. Supplemental materials are available for this article.
