General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product has been enhanced for catalytic efficiency. Click here for more information.
[SIPr-H]2Pd2Cl6 is an ionic tetrachloropalladate complex containing 2 equivalents of the cationic imadazolium ligand 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium.

Application

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.

Features and Benefits

[SPr-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 [SIPr-H]2Pd2Cl6 compared to similar Pd-NHC complexes makes the product a more sustainable choice.
  • A competitive price, with a higher Pd percentage than many other Pd-NHC catalysts.

The reaction mechanism leading to the formation of cross-coupling palladium pre-catalysts of the PEPPSI family was investigated. Two intermediates were isolated and proved to be both suitable synthons to the pre-catalysts, with one permitting the design of a novel and
