Selectivity enhancement in functionalization of C–H bonds: A review
Organic & Biomolecular Chemistry, 2010The selectivity is an extremely important characteristic of a chemical reaction. This review deals mainly with supramolecular and nano-chemical approaches to the problem of selectivity enhancement in various functionalizations of C-H compounds. Enzyme mimics is a very fruitful method to achieve the predominant formation of desirable products and ...

Precise Functionalization of Remote C-H Bonds
Chemical Research in Chinese Universities, 2020Remote C-H bond functionalization of arenes with precise control is a recognized extraordinary challenge in organic synthesis. Recently, Yu and Houk et al. developed an elegant strategy to distinguish and functionalize remote Csp2-H bonds of (hetero)arenes within one-bond distance by the interplay of a remote directing template and a transient ...

Cobalt-Catalyzed C-H Bond Functionalization
The ultimate goal of organic synthetic chemistry is to design and synthesize more complex structures from simple molecules. Classic organic synthesis often relies on the manipulations of functional groups. In organic chemistry, the term 'C-H bond functionalization' is used to describe a chemical reaction, in which a C-H bond of a substrate is cleaved ...openaire +3 more sources
