Descrição

Descrição geral

Tris(dibenzylideneacetone)dipalladium(0) (Pd₂(dba)₃) is a versatile compound widely used as a Pd(0) source in various Pd-mediated transformations.[1] 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.[2]

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