N-Heterocyclic carbenes, despite being isolated and characterized three decades ago, still
capture scientists' interest as versatile, modular and strongly coordinating moieties. In the …

Since the discovery of the first stable N-heterocyclic carbene (NHC) in the beginning of the
1990s, these divalent carbon species have become a common and available class of …

Currently, the only compounds known to support fixation and functionalization of dinitrogen
(N2) under nonmatrix conditions are based on metals. Here we present the observation of …

Oxidative addition and reductive elimination are key steps in a wide variety of catalytic
reactions mediated by transition-metal complexes. Historically, this reactivity has been …

Since the latter quarter of the twentieth century, main group chemistry has undergone
significant advances. Power's timely review in 2010 highlighted the inherent differences …

Abstract Discovered in 2005, cyclic (alkyl)(amino) carbenes (CAACs) are among the most
nucleophilic (σ donating) and also electrophilic (π‐accepting) stable carbenes known to …

Small molecules such as H2, N2, CO, NH3, O2 are ubiquitous stable species and their
activation and role in the formation of value-added products are of fundamental importance …

The successful isolation and characterization of an N-heterocyclic carbene in 1991 opened
up a new class of organic compounds for investigation. From these beginnings as academic …

Conspectus Carbenes are compounds that feature a divalent carbon atom with only six
electrons in its valence shell. In the singlet state, they possess a lone pair of electrons and a …

The usage of carbon monoxide (CO) as a C1 feedstock for carbonylation has been an
important subject of numerous studies for over a century. The chemistry in this field has …
