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 …

Carbenes, thought of only as transient species for a long time, have become ubiquitous in
organometallic chemistry. Their interaction with a metal center, which allows for their …

Multifunctionalization from the interception of active intermediates is an attractive synthetic
strategy for the efficient construction of complex molecular scaffolds in an atom and step …

Conspectus Metal carbene plays a vital role in modern organic synthesis. The neutral
divalent carbon of metal carbene renders it an active intermediate throughout a range of …

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

Oxycarbenes have emerged as useful intermediates in synthetic chemistry. Compared to the
widely studied oxycarbene metal complexes bearing Group 6 metals, the synthetic and …

The formal combination of a carbene and an organometallic fragment yields carbene
complexes. They are commonly classified as Fischer-and Schrock-type complexes. While …

Insertion reactions that involve stabilized electrophilic metallocarbenes are of great
importance for installing α‐heteroatoms to carbonyl compounds. Nevertheless, the limited …

Geminal cross couplings using multiple components enable the formation of several
different bonds at one site in the building of tertiary and quaternary alkanes. Nevertheless …

A formal gold‐for‐chromium transmetalation allowed the gold carbenoid species
[Cy3PAuCAr2] NTf2 (11)(Ar= pMeOC6H4‐) to be obtained in crystalline form. The structure …
