Transition-metal-catalyzed oxidative and decarboxylative acylations of sp2 C-H bonds bearing conventional directing groups with various acyl equivalents, such as aldehydes, alcohols, alkylbezenes, α-keto acids, etc. are described. These protocols present an effective and promising route to obtain aryl ketones, which are found to be important precursors for the formation of bioactive molecules and functional materials. Th Read More

Development of cross-coupling chemistry by direct functionalization of C–H or heteroatom–H bonds under oxidative conditions has recently emerged as powerful and ideal methods for the formation of carbon-carbon and carbon-heteroatom bonds. Several transition metal catalysts were successfully utilized for these kinds of transformations over the past several years. Among them, copper salts are of special importance Read More

In green chemistry, the most ideal synthetic route to biaryl compounds, which are important in manufacturing fine chemicals, from non-functionalized starting aromatic materials appears to be the oxidative couplings that directly use two molecules of C–H groups for a new bond-forming event to reduce the synthetic steps and byproduct generation. However, these methods for reacting non-activated aromatic su Read More

Supported ionic liquids refer to ionic liquids that are immobilized on supports (e.g. silica-based materials, magnetic nanoparticles, carbon nanotube, etc.). The synergistic effect of ILs and supports can derive a series of novel performances and properties while retain the advantages of both species. As green media in organic catalytic reactions and asymmetric reactions, they have many advantages over free ionic liquids, inc Read More
