Description

2-(Di-p-Tolylphosphino)Benzaldehyde, 97% is a high-purity organophosphorus ligand featuring a reactive aldehyde functional group. This compound is critical for facilitating and controlling transition metal-catalyzed cross-coupling reactions, which are foundational to modern synthetic chemistry. It is an essential building block for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require precise molecular construction.

Application

• Ligand in Catalysis: Serves as a key ligand for palladium, nickel, and other transition metal catalysts in cross-coupling reactions such as Suzuki, Heck, and Negishi couplings.
• Pharmaceutical Intermediate Synthesis: Used in the research and development of active pharmaceutical ingredients (APIs), enabling the formation of complex carbon-carbon and carbon-heteroatom bonds.
• Agrochemical Production: Employed in the synthesis of novel herbicides, fungicides, and insecticides that require specific, high-yield coupling steps.
• Material Science Research: Acts as a precursor or functionalizing agent in the development of organic electronic materials, polymers, and metal-organic frameworks (MOFs).
• Asymmetric Synthesis: The aldehyde group allows for further derivatization to create chiral phosphine ligands for enantioselective catalysis.
• Academic & Industrial R&D: A valuable reagent for method development and exploratory synthesis in both university laboratories and industrial R&D centers.
