Carbon Materials as Catalytic Tools for Oxidative Dehydrogenations and Couplings in Liquid Phase

Abstract

AbstractCarbocatalysis is a heterogeneous metal-free catalytic technique of high potential for current and future synthetic processes. Carbocatalysts entail heterogeneous materials based on sp2/sp3 interconnected carbons decorated with oxygen functional groups, defects, and other heteroatom dopants. In this short review, we cover a wide range of different carbocatalyzed oxidative dehydrogenation reactions, with particular emphasis on liquid-phase transformations that are relevant for synthetic organic chemists.1 Introduction2 Structures of Catalytic Carbon Materials3 Oxidative Aromatizations with Activated Carbon4 Oxidative Dehydrogenation CH–CH Couplings5 Oxidative Dehydrogenation Coupling of Benzyl Amines6 Oxidations of Alcohols7 Other Oxidative Transformations by Heteroatom-Doped Carbon Materials8 Asphaltene Oxide9 Conclusions and Outlook
