Popis

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)
