설명

일반 설명

[IPr-H]₂Pd₂Cl₆ is an ionic tetrachloropalladate complex containing 2 equivalents of the cationic imadazolium ligand 1,3-bis(2,6-diisopropylphenyl)-1H-imidazol-3-ium.

애플리케이션

Upon treatmeant with a suitable base, a catalytically active Pd-NHC complex can be generated in-situ. Suitable for use in difficult Suzuki-Miyaura and Buchwald-Hartwig cross-couplings reactions of aryl chlorides, and trans-amidation cross-coupling reactions of esters and amides.

특징 및 장점

[IPr-H]₂Pd₂Cl₆ offers similar or greater performance to other similar Pd-NHC precatalysts available while offering several major advatages:

• The precatalyst avoids the use of ′throw away′ stabilizing ligands often used in similar Pd-NHC complexes.
• The more sustainable synthesis of [IPr-H]₂Pd₂Cl₆ compared to similar Pd-NHC complexes makes the product a more sustainable choice.
• A competitive price, with a higher Pd percentage than other Pd-NHC catalysts.
