Description

Dichloro[1,3-Bis(2-Methylphenyl)-2-Imidazolidinylidene](2-Isopropoxyphenylmethylene)Ruthenium(II) is a highly specialized, second-generation Grubbs-Hoveyda type olefin metathesis catalyst, valued for its exceptional activity and thermal stability. This organometallic complex is engineered to facilitate challenging cross-metathesis and ring-closing metathesis (RCM) reactions with high selectivity and yield. It is an essential tool for research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors, enabling the efficient synthesis of complex molecules and novel polymers.

Application

• Pharmaceutical Intermediate Synthesis: Key catalyst for constructing complex macrocyclic and heterocyclic scaffolds in active pharmaceutical ingredient (API) development via ring-closing metathesis.
• Agrochemical Research: Used in the synthesis of novel, biologically active compounds with potential herbicidal or insecticidal properties.
• Advanced Polymer Chemistry: Enables the production of specialty polymers with tailored properties through ring-opening metathesis polymerization (ROMP) and acyclic diene metathesis (ADMET).
• Fine Chemical & Fragrance Manufacturing: Facilitates the creation of unique olefinic structures used in high-value flavor and fragrance ingredients.
• Academic & Industrial R&D: A critical reagent for methodological development in organic synthesis and catalysis studies.
• Material Science: Applied in the synthesis of functionalized surfaces and novel organic-inorganic hybrid materials.
