Cyclic(alkyl)(amino) carbenes (CAACs) are a class of stable singlet carbene ligands that feature one amino and one sp3 alkyl group adjacent to the carbene carbon atom. CAACs are a subset of N-heterocyclic carbenes (NHCs) in which the replacement of...
A persistent carbene (also known as stable carbene) is an organic molecule whose natural resonance structure has a carbon atom with incomplete octet (a carbene), but does not exhibit the tremendous instability typically associated with such...
Carbodicarbenes (CDCs) are a subclass of carbon(0) compounds known as carbones consisting of a divalent central carbon atom stabilized by two neutral carbene donors, most commonly N-heterocyclic carbenes (NHCs) or cyclic (alkyl)(amino)carbenes...
In chemistry, amines (, UK also ) are organic compounds that contain carbon–nitrogen bonds. Amines are formed when one or more hydrogen atoms in ammonia are replaced by alkyl or aryl groups. The nitrogen atom in an amine possesses a lone pair of...
Germylenes are a class of germanium(II) compounds with the general formula :GeR2. They are heavier carbene analogs. However, unlike carbenes, whose ground state can be either singlet or triplet depending on the substituents, germylenes have...
In chemistry, a diradical is a molecular species with two electrons occupying molecular orbitals (MOs) which are degenerate. The term "diradical" is mainly used to describe organic compounds, where most diradicals are extremely reactive and...
A borylene is the boron analogue of a carbene. The general structure is R-B: with R an organic moiety and B a boron atom with two unshared electrons. Borylenes are of academic interest in organoboron chemistry.
In chemistry, the oxidation state, or oxidation number, is the hypothetical charge of an atom assuming all of its bonds to other atoms are fully ionic. It describes the degree of oxidation (loss of electrons) of an atom in a chemical compound....
Guy Bertrand, born on July 17, 1952, at Limoges is a chemistry professor at the University of California, San Diego. Bertrand obtained his B.Sc. from the University of Montpellier in 1975 and his Ph.D. from the Paul Sabatier University, Toulouse, in...
