一般描述

[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.

应用

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.

特点和优势

[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.
