The functionalisation of C–H bonds has been an enormous achievement in synthetic
methodology, enabling new retrosynthetic disconnections and affording simple synthetic …

In this review we present the transformations that have been developed with ynamides and
free radicals. These reactions involve carbon‐, heteroatom‐or even metalloid‐centered …

The alkylation and heteroarylation of unactivated tertiary, secondary, and primary C (sp3)–H
bonds was achieved by employing an acridinium photoredox catalyst along with readily …

Readily available and facilely tunable pyridine N-oxides have been developed as effective
photoinduced hydrogen-atom-transfer (HAT) catalysts for site-selective C–H …

Bifunctional reagents that serve as dual coupling partners with an activating species have
emerged as valuable synthetic tools in organic chemistry. They allow for the development of …

Heterocyclic N‐oxides are prevalent in numerous natural products with broad applications in
pharmaceuticals, agrochemicals, material sciences, and asymmetric synthesis. Owing to …

By utilizing an underexplored reactivity mode of N-aminopyridinium ylides, we developed
the visible-light-induced ortho-selective aminopyridylation of alkenes via radical-mediated 1 …

The N-heterocyclic carbene/photo-cocatalyzed oxidative Smiles rearrangement of O-aryl
salicylaldehydes was developed. Both electron-deficient and electron-rich aryls worked well …

Pyridine derivatives are one of the most important moieties in the synthesis of various
biologically active compounds containing heterocyclic ring. But, due to the low reactivity of …

Ortho-alkylated and ortho-acylated pyridines have been conveniently synthesized from
pyridine N-oxides and alkynes under visible-light-mediation in a metal-free manner. The …
