The applications of copper (Cu) and Cu-based nanoparticles, which are based on the earth-
abundant and inexpensive copper metal, have generated a great deal of interest in recent …

Copper nanoparticles have been explored as a new class of heterogeneous catalyst in
various chemical transformations. This review surveys the most useful organic …

A transition metal‐free direct C‐3 arylation of quinoxalin‐2 (1H)‐ones with arylamines has
been explored. This reaction proceeded smoothly through a radical process under mild …

The upsurge interest in the development of efficient methodologies for the construction of
nitrogen‐containing frameworks via the use of expedient reagents have been creating a …

Activation of H–H, Si–H, and C–H bonds through σ-bond coordination has grown in the past
30 years from a scientific curiosity to an important tool in the functionalization of …

Nitrogen-doped graphene (NG) has recently attracted much interest because of its ability to
fix the metal nanoparticles (NPs). In this study, NG materials with a nitrogen content of 4.5 …

In this review, we give a concise but complete overview of methods describing the use of
aryl diazonium salts in palladium-catalyzed reactions under safe conditions from a …

This review gives an overview of the generation of aryl radicals, mediated by transition
metals, and their use for the C H arylation of heteroarenes. The different sources of …

A novel ligand-free, transition metal-free direct C–H functionalization of quinones with
diaryliodonium salts has been developed for the first time. The transformation was promoted …

The direct functionalization of quinones has always fascinated research communities due to
their biological and redox activities and subsequent application. Quinone motifs play a vital …
