In the last few decades, the transition metal‐catalyzed activation of inert C− H bonds has led
to a fundamental change in the field of synthetic chemistry. Most of these C− H activation …

Ruthenium complexes are well known as remarkable pre-catalysts for challenging C–H
bond functionalizations. Combining them with other types of chemical reactions in a tandem …

Azides are important intermediates in organic synthesis. They can function as precursors to
form amines, amides, quinolones, pyridines, triazoles, amidines, indoles, and so on …

Amides reacted with NaN3 to give the acyl azides in DMF at 25° C and produce the
symmetrical ureas in THF/H2O at 80° C via the sequential reaction of acyl substitution and …

The chemistry of phosphoranyl radicals has received increasing attention in recent years.
Here, we report the generation of amidyl radicals through photocatalytic deoxygenation of …

Organic syntheses based on the activation of C–H bonds catalysed by transition metals (TM)
are of great interest because new pathways can be designed that were not previously …

A cobalt-catalyzed annulation of the C (sp2)–H/N–H bond of indoloamides with alkynes
assisted by 8-aminoquinoline is reported for the synthesis of six-membered indololactams …

A new traceless directing group, 2-(hydroxymethyl) pyridine, has been reported for the Cp*-
free cobalt-catalyzed C–H activation/annulation reaction to synthesize isoquinolinones. The …

This review is intended to highlight the most useful approaches for the synthesis of indole
derivatives (azaindoles, carbazoles, carbolines, indazoles, 3H‐indoles, indolines …

Dioxazolones and phosphines have been used to access N‐acyl iminophosphoranes in
copper (I) catalysis under simple thermal conditions. The synthetic utility of this protocol is …
