Description

Lithium Dimethyldiphenylborate(1-) is a versatile organoborate salt widely utilized as a key reagent in advanced organic synthesis. Its primary value lies in its ability to act as a potent nucleophile and a source of a dimethylphenylborate anion, facilitating critical carbon-carbon and carbon-heteroatom bond-forming reactions. This compound is essential for researchers and process chemists in the pharmaceutical, agrochemical, and materials science industries who require high-purity, reliable intermediates for complex molecule construction.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: Serves as a crucial transmetalation agent for the palladium-catalyzed coupling of aryl halides, enabling the synthesis of biaryl structures.
• Nucleophilic Addition to Carbonyls: Acts as a source of a stabilized carbanion for the 1,2-addition to aldehydes and ketones, producing secondary and tertiary alcohols.
• Asymmetric Synthesis: Employed in the preparation of chiral boronate esters, which are pivotal intermediates for enantioselective transformations in pharmaceutical API development.
• Polymer Chemistry: Used as an initiator or modifying agent in the synthesis of specialty polymers and advanced materials with tailored properties.
• Organic Light-Emitting Diodes (OLEDs): Functions as a precursor or dopant in the fabrication of electron-transport layers and emissive materials.
• Catalyst Ligand Synthesis: Provides a borate moiety for the construction of novel ligand frameworks used in homogeneous catalysis.

Quality Control

Our Lithium Dimethyldiphenylborate(1-) is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high chemical purity. Each lot undergoes comprehensive analytical testing, including NMR spectroscopy and titration methods, to verify identity and assay. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, this material should be handled and stored under an inert atmosphere (argon or nitrogen) to prevent decomposition. Recommended long-term storage temperature is 2-8°C.
