Nitrous oxide, commonly known as “laughing gas”, is formed as a by-product in several
industrial processes. It is also readily available by thermal decomposition of ammonium …

Over decades diazoalkenes (R2C= C= N2) were postulated as reactive intermediates in
organic chemistry even though their direct spectroscopic detection proved very challenging …

Precise modification of a chemical site in a molecule at the single-atom level is one of the
most elegant yet difficult transformations in chemistry. A reagent specifically designed for …

Abstract The venerable 1, 3-dipolar cycloaddition has been widely used in organic synthesis
for the construction of various heterocycles. However, in its century-long history, the simple …

This perspective describes the development of zero-valent species E n (0) of group 13–15
elements. Computational studies providing reinterpretation of bonding involved in well …

Diazo compounds are valuable reagents in synthesis but usually require the use of
potentially explosive or toxic starting materials. Here, we report the synthesis and isolation of …

Homometallic copper complexes with alkenylidene ligands are discussed as intermediates
in catalysis but the isolation of such complexes has remained elusive. Herein, we report the …

This Perspective article highlights the recent development of mesoionic N-heterocyclic
olefins (mNHOs), where the exo-cyclic olefinic carbon is not bonded to strongly electron …

Diazoalkenes readily react with tert‐butylphosphaalkyne (tBuCP) and white phosphorus
(P4) to afford novel phosphorus heterocycles, 3H‐1, 2, 4‐diazamonophospholes and 1, 2, 3 …

Recently, stable diazoalkenes have received significant attention as a new substance class
in organic chemistry. While their previous synthetic access was exclusively limited to the …
