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 …

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

Asymmetric catalysis of photochemical cycloadditions has been limited by the challenge of
suppressing the unselective background reaction. Here, we report that the high cross …

Ring-closing metathesis (RCM) of dienes is one of the most important methodologies now in
use for the assembly of cyclic organic compounds. First employed by Villemin and by Tsuji …

Since the isolation and crystallographic characterization of the first stable N-heterocyclic
carbene in early 1991, 1 nucleophilic diaminocarbenes (also known as “Arduengotype” …

There have been numerous significant advances in catalytic olefin metathesis (OM) during
the past two decades. Such progress has transformed this important set of reactions to …

Ruthenium-based Hoveyda-type olefin metathesis catalysts bearing novel rigid spirocyclic
alkyl amino carbenes (CAACs) have been developed. They are characterized by …

The past decade has seen N-heterocyclic carbenes (NHC) emerging as a credible
alternative to ubiquitous tertiary phosphines as ligands in organic and organometallic …

Over the past decade, ruthenium-mediated metathesis transformations, including
polymerization reactions, cross-metathesis, ring-closing metathesis, enyne metathesis, ring …
