C–H Functionalization of Azines

Chemical Reviews, 2017
Azines, which are six-membered aromatic compounds containing one or more nitrogen atoms, serve as ubiquitous structural cores of aromatic species with important applications in biological and materials sciences. Among a variety of synthetic approaches toward azines, C-H functionalization represents the most rapid and atom-economical transformation, and

Intramolecular Redox‐Triggered CH Functionalization

Angewandte Chemie International Edition, 2012
Sacrifice for the team: A one-pot method achieves remote functionalization at the α-position of an amine moiety through the sacrificial reduction of a neighboring group. The process takes advantage of an intramolecular redox reaction, thereby avoiding the need for any external oxidants.

Photocatalytic Late-Stage C–H Functionalization

Chemical Reviews, 2023
The emergence of modern photocatalysis, characterized by mildness and selectivity, has significantly spurred innovative late-stage C-H functionalization approaches that make use of low energy photons as a controllable energy source. Compared to traditional late-stage functionalization strategies, photocatalysis paves the way toward complementary and/or

Chandrasekhar’s H-function revisited

Journal of Quantitative Spectroscopy and Radiative Transfer, 2020
Abstract The Chandrasekhar H-function plays an important role in a wide class of problems of analytical radiative transfer theory. The H-function is the solution of well-known integral equations, both non-linear and linear. The physics of a particular problem under consideration determines the form of the so-called characteristic and dispersion ...

Asymmetric C-H Functionalization

2022
Asymmetric C–H functionalization has received increasing attention from researchers in the past decade due to its significance in the construction of molecular complexity without the need to preactivate. Distinguishing the reactivity among multiple C–H bonds in a single molecule presents very challenging issues in organic synthesis and requires ...

Platinum-Catalyzed C–H Functionalization

Chemical Reviews, 2016
Recent developments in C-H bond activation and functionalization by Pt complexes are surveyed. Topics include the following: fundamental mechanistic investigations of C-H activation; stoichiometric intra- and intermolecular C-H activation; reactions of dioxygen with Pt(II) complexes that may be relevant to substrate oxygenation; and both stoichiometric

Iron-Catalyzed C–H Functionalization Processes

Topics in Current Chemistry, 2016
Iron-catalyzed C-H activation has recently emerged as an increasingly powerful tool for the step-economical transformation of unreactive C-H bonds. Particularly, the recent development of low-valent iron catalysis has set the stage for novel C-H activation strategies via chelation assistance.
