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 …

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 …

While the fundamental series of [2+ 2] cycloadditions and retro [2+ 2] cycloadditions that
make up the pathways of ruthenium-catalysed metathesis reactions is well-established, the …

Rationally designed Ru-based catalysts for efficient Z-selective olefin metathesis are
featured. The new complexes contain a dithiolate ligand and can be accessed in a single …

The mechanism of Ru-catalyzed ring-opening metathesis polymerization (ROMP) is studied
in detail using a pair of third generation ruthenium catalysts with varying sterics of the N …

Grubbs–Hoveyda-type complexes with variable 4-R (complexes 1: 4-R= NEt2, O i Pr, H, F,
NO2) and 5-R substituents (complexes 2: 5-R= NEt2, O i Pr, Me, F, NO2) at the 2-isopropoxy …

The asymmetric synthesis of [7] helicene was accomplished in good ee (80%) by kinetic
resolution by means of asymmetric olefin metathesis. Three key factors contributed to the …

The mechanism of ring-opening metathesis polymerization (ROMP) for a set of
functionalized norbornenyl monomers initiated by a Grubbs third generation precatalyst …

The phosphonium alkylidene [(NHC) Cl2Ru= CH (PCy3)]+[B (C6F5) 4]-, 1,(NHC= N-
heterocyclic carbene, Cy= cyclohexyl, C6H11) reacts with 2.2 equiv of ethylene at− 50° C to …
