| Summary: | The oxidation of alcohols to carbonyl compounds is an important reaction in synthetic organic chemistry. While stoichiometric oxidants are effective for this transformation, they often produce large amounts of toxic waste, which renders them unacceptable from an environmental and economic perspective. Consequently, there is a strong impetus to develop catalytic processes that utilize environmentally friendly, inexpensive primary oxidants, the use of molecular oxygen being particularly attractive. Recently, hydrotalcites have attracted attention as both catalysts and catalyst supports for the selective oxidation of alcohols to ketones and aldehydes, using either oxygen or TBHP as the oxidant. This review is intended to provide a comprehensive summary of work performed in this area to date. The effects of composition and structure on catalyst properties are highlighted, and mechanistic aspects are discussed.
Hydrotalcite-like compounds are reviewed for their use as catalysts and catalyst supports in the oxidation of alcohols to their corresponding carbonyl compounds. |

| Bibliography: | Dr Mark Crocker received BSc. and PhD degrees in chemistry from the University of Bristol in the United Kingdom, and spent two years as a NATO postdoctoral researcher at the University of Wisconsin-Madison. Thereafter he spent 15 years working in industry for first Shell Research and then Degussa's automotive catalyst division. In 2003 he moved to the University of Kentucky (UK) where he is currently a Professor in the Department of Chemistry and an Associate Director of the Center for Applied Energy Research. At UK he leads a research group focusing on biofuels and environmental catalysis. Justin Mobley is a PhD candidate under the supervision of Dr Mark Crocker at the University of Kentucky. Prior to pursuing his PhD, Justin studied chemistry at Western Kentucky University where he received a Bachelor of Science Degree. His current research interests include catalytic aerobic oxidations of alcohols with hydrotalcite-like catalysts, oxidative catalytic depolymerization of lignin, and NMR characterization of lignin (specifically heteronuclear single quantum coherence and quantitative P NMR). 31 |
