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

In this contribution, we provide a comprehensive overview of C–H activation methods
promoted by NHC–transition metal complexes, covering the literature since 2002 (the year …

Heteroatom-centered diradical (oid) s have been in the focus of molecular main group
chemistry for nearly 30 years. During this time, the diradical concept has evolved and 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 …

This review considers phosphine and N-heterocyclic carbene complexes of gold (I) that are
used as (pre) catalysts for a range of reactions in organic synthesis. These are divided …

Mesoionic carbenes are a subclass of the family of N-heterocyclic carbenes that generally
feature less heteroatom stabilization of the carbenic carbon and hence impart specific donor …

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 …

Carbenes (R2C:), compounds with a divalent carbon atom containing only six valence shell
electrons, have evolved into a broader class with the replacement of the carbene carbon or …

Natural bond orbital (NBO) analysis is one of many available options for 'translating'
computational solutions of Schrödinger's wave equation into the familiar language of …
