Ruthenium-based olefin metathesis catalysts, known for their functional group tolerance and
broad applicability in organic synthesis and polymer science, continue to evolve as an …

Donor and donor–donor carbenes are two important kinds of carbenes, which have
experienced tremendous growth in the past two decades. This review provides a …

The fascinating story of olefin (or alkene) metathesis (eq 1) began almost five decades ago,
when Anderson and Merckling reported the first carbonrcarbon double-bond rearrangement …

N-Heterocyclic carbenes (NHCs) are defined as singlet carbenes, in which the divalent
carbenic center is connected directly to at least one nitrogen atom within the heterocycle. 1 …

N-Heterocyclic carbene (NHC) ligands, introduced as analogues to phosphines, are recently
getting wide attention in the design of diverse homogeneous catalytic systems. 1-6 During …

Catalytic olefin metathesis—through which pairs of C= C bonds are reorganized—
transforms simple molecules to those that are complex and precious. This class of reactions …

Discovered in 2005, cyclic (alkyl)(amino) carbenes (CAACs) have led to numerous
discoveries in the field of ruthenium olefin metathesis, until then largely dominated by the …

The strong σ-donor but poor π-acceptor abilities of N-heterocyclic carbenes (NHCs) result in
chemical stability and coordination versatility, thus allowing them to coordinate with many …

Oxa-and azabicyclic alkenes can be readily activated by transition-metal complexes with
facial selectivity, because of the intrinsic reactivity of strained bicyclic structures …

Olefin metathesis is a versatile synthetic tool for the redistribution of alkylidene fragments at
carbon–carbon double bonds. This field, and more specifically the development of task …
