Discovered as organometallic curiosities in the 1970s, carbene radicals have become a
staple in modern-day homogeneous catalysis. Carbene radicals exhibit nucleophilic radical …

This review summarizes experimental and theoretical studies of transition metal complexes
with two types of novel metal-carbon bonds. One type features complexes with carbones …

Substitution of a C= C bond by an isoelectronic B–N bond is a well-established strategy to
alter the electronic structure and stability of acenes. BN-substituted acenes that possess …

Molecules with different resonance structures of similar importance, such as
heterocumulenes and mesoionics, are prominent in many applications of chemistry …

This review is dedicated to the chemistry of stable and isolable species that bear two lone
pairs at the same C center, ie, geminal dianions, stabilized by main group elements. Three …

Carbones are divalent carbon (0) species that contain two lone pairs of electrons. Herein,
we have prepared the first known stable and isolable free bis‐(carbone) pincer framework …

The first examples of carbodicarbene (CDC)-s-block complexes have been synthesized. The
addition of base or reducing agent to a CDC–beryllium (chloride)(hexamethyldisilazide) …

Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) has been widely
employed to characterize transition metal complexes. However, because of the high degree …

Herein, a new type of carbodicarbene (CDC) comprising two different classes of carbenes is
reported; NHC and CAAC as donor substituents and compare the molecular structure and …

Ligand noninnocence has been well-established for transition metal complexes containing
diatomics such as NO and O 2, and bidentate chelates like quinones/semiquinones …
