General description

Palladium(II) trifluoroacetate is a catalyst used in Suzuki-Miyaura, Heck, and Stille cross-coupling reactions.

Application

Application Guide for Palladium Catalyzed Cross-Coupling Reactions
Catalyst used for the mild decarboxylation of electron-rich aromatic acids and the direct cross-coupling of unactivated arenes.
Catalyzes the selective allylic oxidation of geranylacetone and other olefins to their allyl acetates, which can then be converted to keto alcohols.

Molecular oxygen can replace sacrificial olefins as the hydrogen acceptor in the palladium trifluoroacetate catalyzed dehydrogenation of cyclohexene and related cyclic olefins into aromatics. One of the major drawbacks of the homogeneous system is the tendency of the palladium trifluoroacetate

A palladium-catalyzed aromatic decarboxylation reaction has been developed. With electron-rich aromatic acids, the reaction proceeds efficiently under fairly mild conditions in good yields. The method was useful with complex functionalized substrates containing hindered carboxylic acids.

The industrially important coupling of aromatic compounds has generally required differential prefunctionalization of the arene coupling partners with a halide and an electropositive group. Here we report that palladium, in conjunction with a copper oxidant, can catalyze the cross-coupling of
