Organocatalysis in Inert C–H Bond Functionalization

Chemical Reviews, 2017
As two coexisting and fast-growing research fields in modern synthetic chemistry, the merging of organocatalysis and C-H bond functionalization is well foreseeable, and the joint force along this line has been demonstrated to be a powerful approach in making inert C-H bond functionalization more viable, predictable, and selective.

C-H Bond Functionalization in Complex Organic Synthesis

Science, 2006
Direct and selective replacement of carbon-hydrogen bonds with new bonds (such as C–C, C–O, and C–N) represents an important and long-standing goal in chemistry. These transformations have broad potential in synthesis because C–H bonds are ubiquitous in organic substances. At the same time, achieving selectivity among many different C–H bonds remains a

C−H Bond Functionalization by Mechanochemistry

Chemistry – A European Journal, 2017
AbstractThe advances made in the mechanosynthesis of inorganic and organometallic complexes and the excellent past developments with metal‐catalyzed cross‐coupling reactions by high‐speed ball milling have sufficienly laid the ground work for the merging of C−H functionalization and mechanochemical techniques.

1.3 C—H Bond Functionalization

2017
AbstractThis chapter deals with C—H bond functionalization catalyzed by N-heterocyclic carbene transition-metal complexes. The C—H bond functionalizations have been classified with respect to the hybridization of the carbon atom and the reaction type.

CH Bond Functionalization through Intramolecular Hydride Transfer

Angewandte Chemie International Edition, 2014
AbstractKnown for over a century, reactions that involve intramolecular hydride‐transfer events have experienced a recent resurgence. Undoubtedly responsible for the increased interest in this research area is the realization that hydride shifts represent an attractive avenue for CH bond functionalization.

Functionalization of C-H Bonds by Photoredox Catalysis

The Chemical Record, 2017
Visible-light photoredox catalysis has been successfully used in the functionalization of inert C-H bonds including C(sp2 )-H bonds of arenes and C(sp3 )-H bonds of aliphatic compounds over the past decade. These transformations are typically promoted by the process of single-electron-transfer (SET) between substrates and photo-excited photocatalyst ...
