Description

Bis{2-[(11Br)-3,5-Dihydro-4H-Dinaphtho[2,1-C:1',2'-E]Phosphepin-4-Yl]Ethyl}Amine, Min. 97% is a high-purity, advanced phosphine ligand derivative, essential for facilitating complex catalytic transformations in organic synthesis. Its value lies in its ability to act as a highly effective ligand for transition metals, enabling challenging cross-coupling and asymmetric hydrogenation reactions with superior selectivity and yield. This compound is critically needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries for the development of novel active ingredients and high-value intermediates.

Application

• As a specialized ligand in palladium-catalyzed cross-coupling reactions (e.g., Suzuki-Miyaura, Buchwald-Hartwig amination).
• For asymmetric catalysis in the synthesis of chiral pharmaceutical intermediates and active pharmaceutical ingredients (APIs).
• In homogeneous catalysis research for developing new methodologies in C-H activation and C-C bond formation.
• As a key precursor for the synthesis of more complex, tailor-made phosphine ligands for specific catalytic applications.
• In academic and industrial R&D for exploring novel reaction pathways and optimizing process efficiency.
• For the manufacture of high-performance materials, such as organic light-emitting diodes (OLEDs) and electronic chemicals.
