Description

1,2-Bis[1,3-Bis(2,6-Di-I-Propylphenyl)Imidazol-2-Ylidene]Diphosphine is a sophisticated, sterically demanding N-heterocyclic carbene (NHC)-based diphosphine ligand, representing a pinnacle of modern organometallic catalyst design. This compound matters for its exceptional ability to stabilize reactive metal centers and direct catalytic transformations with high selectivity and activity, enabling more efficient and sustainable chemical processes. It is critically needed by researchers and manufacturers in the pharmaceutical, fine chemical, and advanced materials sectors for developing next-generation catalysts for cross-coupling, hydrogenation, and other pivotal synthetic reactions.

Application

• As a pre-ligand for homogeneous catalysis, forming highly active transition metal complexes (e.g., Pd, Pt, Ni, Rh).
• Enabling challenging C-C and C-X (X = N, O) bond-forming cross-coupling reactions (e.g., Suzuki-Miyaura, Buchwald-Hartwig) under mild conditions.
• Facilitating asymmetric hydrogenation and other stereoselective transformations in pharmaceutical intermediate synthesis.
• Acting as a supporting ligand in polymerization catalysis for the production of specialty polymers and materials.
• Use in academic and industrial R&D for exploring new catalytic cycles and reaction mechanisms.
• Potential application in materials science for the synthesis of novel organometallic frameworks and precursors.

Quality Control

Our 1,2-Bis[1,3-Bis(2,6-Di-I-Propylphenyl)Imidazol-2-Ylidene]Diphosphine is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity, essential for reproducible catalytic performance. Each lot undergoes rigorous analytical characterization, including NMR (1H, 13C, 31P) and HPLC analysis. Certificates of Analysis (COA) detailing purity and identity are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store under an inert atmosphere (argon or nitrogen) at 2-8°C. This compound is easily oxidized and light-sensitive; prolonged exposure to air, moisture, or light should be avoided to maintain efficacy. Allow the sealed container to reach ambient temperature before opening to prevent condensation.
