Popis

General description

[Pd(OAc)₂]₃ is a palladium coordination complex and a heterogenous metal catalyst that is widely used in organic synthesis such as transmetalation, insertion, oxidative addition, direct homocoupling of aryl halides, Buchwald-Hartwig reaction of C-N bond formation, reduction of alkynes, and reductive elimination reactions. It is also employed as a starting material for the synthesis of other Pd(II) compounds as well as for the preparation of active palladium catalysts for Suzuki-Miyaura cross-coupling and C-H functionalization reactions.

Application

Application Guide for Palladium Catalyzed Cross-Coupling Reactions

[Pd(OAc)₂]₃ can be used as a:

• Catalyst for the regioselective anti-hydrochlorination of the terminal and internal alkynes.
• Precursor to prepare a heterogeneous palladium complex catalyst for the Heck-Coupling reaction and Sonogashira cross-coupling reaction.
