Collection: Olefin Metathesis [Catalysis]
Olefin Metathesis [Catalysis] — covers transition metal catalysts of the Grubbs and Hoveyda-Grubbs generations and their ruthenium- and titanium-based derivatives, including alkylidene reagents such as Tebbe and Petasis for olefin metathesis and methylenation reactions.
Olefin metathesis catalysts are widely used in organic synthesis for ring-closing metathesis (RCM), cross metathesis, and ROMP polymerization, supporting the formation of macrocyclic rings, functional polyolefins, and building blocks in materials chemistry research and natural product synthesis. Reagents such as Tebbe and Dimethyltitanocene are used for converting carbonyls into alkenes (modified Wittig methylenation).
Example products in this collection: TCI U0141 2055540-61-7 UltraCat (contains 5% Nitromethane at maximum), TCI C1411 67719-69-1 Tebbe Reagent (ca. 0.5mol/L in Toluene), TCI U0116 2106819-64-9 UltraNitroCat, TCI D4100 1271-66-5 Dimethyltitanocene (5% in Tetrahydrofuran/Toluene), TCI A3009 1414707-08-6 AquaMet, TCI N1060 502964-52-5 nitro-Grela, TCI P2004 250220-36-1 (3-Phenyl-1H-inden-1-ylidene)bis(tricyclohexylphosphine)ruthenium(II) Dichloride.
Consider the ligand type (second-generation NHC vs. first-generation phosphine), stability toward air and moisture, and the formulation (pure solid or solution in solvents such as toluene/THF), which affect ease of handling. All products are genuine products of Tokyo Chemical Industry (TCI) Japan, with purity, packaging, and storage conditions listed on each item's page.
