Benzylidene-bis(tricyclohexylphosphine)dichlororuthenium (Grubbs Catalyst 1st Generation) (CAS: 172222-30-9) is a ruthenium catalyst. It is a complex of ruthenium and two triphenylphosphine ligands, which is a type of coordination complex. This compound is used in a variety of research applications, such as the synthesis of organic compounds and the study of biochemical and physiological effects.
Grubbs Catalyst 1st Generation belongs to a class of coordination complexes known as olefin metathesis catalysts. Olefin metathesis is a chemical reaction in which two alkene molecules are coupled through the exchange of carbon-carbon double bonds. Olefin metathesis occurs when a metal catalyst is present to mediate the reaction.
Robert H. Grubbs discovered the first olefin metathesis catalyst in the 1990s, and for his work, he was awarded the Nobel Prize in Chemistry in 2005. Robert discovered Grubbs Catalyst 1st Generation, Grubbs Catalyst 2nd Generation, Hoveyda-Grubbs Catalyst (Amir H. Hoveyda). The first-generation Grubbs catalyst is essentially the first commercial Grubbs catalyst.
Ruthenium catalysts are highly resistant to polar monomers, enabling the polymerization of many polar monomers to prepare cyclic olefin copolymers. Cyclic olefin copolymers can be widely used in the manufacture of various optical, information, electrical, and medical materials.
Catalysis of olefin metathesis including ring-closing of dienes, cross metathesis and ring-opening methathesis polymerizations (ROMP).
First metathesis catalyst to be widely used in organic synthesis. Useful for acyclic diene metathesis polymerization (ADMET), Ring-Opening Metathesis Polymerization (ROMP) of strained cyclic olefins, ring opening metathesis (ROM), olefin cross metathesis (CM) and ring closing metathesis (RCM) of terminal olefins under a variety of reactions conditions.
The Grubb catalyst has many advantages: it is easy to synthesize, very active and stable, not only stable to air, but also can maintain catalytic activity in the presence of water, acid, alcohol or other solvents (first generation), and has a strong tolerance to the functional groups of olefin. It is the most widely used olefin complex decomposition catalyst and has a wide range of applications in organic synthesis.
