Readily accessible and shelf-stable 1, 2, 3-triazole and its analogues such as pyridotriazole,
triazoloindole, benzotriazole, and thiadiazole exist in equilibrium with their ring-opened …

Metal-stabilized carbenes derived from diazo compounds have become broadly useful
reactive intermediates for organic synthesis. This tutorial review will describe the recent …

Metal carbenes usually possess versatile reactivities that are controlled by the presence of
both the metals and the ligands. Diazo compounds are commonly used for the generation of …

In recent years, α‐imino rhodium carbene complexes derived by ring‐opening of N‐sulfonyl‐
1, 2, 3‐triazoles have attracted much attention from organic chemists. Many transformations …

Suitably substituted electron-deficient 1, 2, 3-triazoles exist in equilibrium with their ring-
opened α-diazoimine tautomers. This phenomenon was used to facilitate the generation of …

The generation of metal-containing 1, 3-dipoles from metal carbenes represents a significant
advance in 1, 3-dipolar cycloaddition reactions. However, these transformations have so far …

The first rhodium (II)‐catalyzed aza‐[4+ 3] cycloadditions of 1‐sulfonyl 1, 2, 3‐triazoles with
1, 3‐dienes have been developed, and enable the efficient synthesis of highly functionalized …

The asymmetric denitrogenative cycloaddition has emerged as a powerful tool to build chiral
aza-heterocyles. However, only one example of asymmetric denitrogenative cycloaddition of …

During the past few decades, there has been considerable growth in the development of
denitrogenative reactions of triazole skeletons to construct valuable cyclic compounds …

A general method for the formation of fused dihydroazepine derivatives from 1‐sulfonyl‐1, 2,
3‐triazoles bearing a tethered diene is reported. The process involves an intramolecular …
