Description

Di(2-Butenyl)Zinc is a highly reactive organozinc reagent characterized by its two butenyl groups bonded to a central zinc atom. This compound matters as a versatile and selective reagent for carbon-carbon bond formation, particularly in cross-coupling and carbozincation reactions. It is primarily needed by R&D chemists and process development teams in the pharmaceutical, agrochemical, and advanced materials industries for synthesizing complex organic molecules and fine chemicals.

Application

• Cross-Coupling Reactions: A key reagent in Negishi-type cross-coupling with aryl or vinyl halides for the synthesis of substituted alkenes.
• Carbozincation of Alkynes: Used to add the butenyl group across carbon-carbon triple bonds, providing access to functionalized dienes.
• Fine Chemical Synthesis: Intermediate in the production of complex molecules for pharmaceutical active ingredients and agrochemicals.
• Polymer Chemistry: Can act as an initiator or co-catalyst in the polymerization of certain monomers for specialty polymers.
• Organic Synthesis Research: A valuable tool in academic and industrial R&D for exploring new synthetic methodologies.
• Asymmetric Synthesis: When used with chiral ligands, it can facilitate the creation of chiral centers in target molecules.

Quality Control

Our Di(2-Butenyl)Zinc is produced and handled under strict inert atmosphere conditions to ensure purity and reactivity. Each batch undergoes rigorous quality testing, including assay and impurity profiling, to ensure compliance with stringent industry standards. Certificates of Analysis (COA) detailing specific batch results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile, hygroscopic (moisture-sensitive), and easily oxidized nature, this product must be stored under an inert atmosphere (argon or nitrogen) at recommended temperatures between 2°C and 8°C. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids, oxidizing agents, and water.
