General description

Tris(dibenzylideneacetone)dipalladium(0) (Pd2(dba)3) is a versatile compound widely used as a Pd(0) source in various Pd-mediated transformations. Pd2(dba)3 is known for its high reactivity and ability to facilitate oxidative addition reactions. It is prepared by reacting palladium salts with dibenzylideneacetone ligands. It acts as a catalyst for several reactions including Suzuki cross-coupling, Heck coupling, arylation, Buchwald-Hartwig amination, and fluorination. It is often used in catalytic amounts and has been shown to be effective in promoting coupling reactions between aryl halides and boronic acids.

For small scale and high throughput uses, product is also available as ChemBeads (919772)

JosiPhos CyPF-tBu and palladium give catalyst for alkoxylation of activated heteroaryl halides with primary, secondary, and tertiary alcohols

A variety of transition-metal catalysts for the Suzuki coupling reaction are now available in our catalog. The majority of these catalysts are palladium- and nickelbased, typically utilizing phosphine-derived ligands.

The Heck reaction is the palladium catalyzed cross-coupling reaction between alkenes and aryl or vinyl halides (or triflates) to afford substituted alkenes.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
