Anwendungen

Tris(dibenzylideneacetone)dipalladium(0) is the most widely used Pd0 precursor complex in synthesis and catalysis, in particular as a catalyst for various coupling reactions. It is used as a catalyst precursor for palladium-catalyzed carbon-nitrogen bond formation, conversion of aryl chlorides, triflates and nonaflates to nitroaromatics. It is used as catalyst for the synthesis of epoxides, alpha-arylation of ketones, in combination with BINAP for the asymmetric heck arylation of olefins, site-selective benzylic sp3 palladium-catalyzed direct arylation and homoallylic diamination of terminal olefins. It also used for palladium-catalyzed one-pot synthesis of tricyclic indolines, in the Suzuki-Miyaura coupling of 2-pyridyl nucleophiles and cross-coupling of aryl halides with aryl boronic acids.

Bemerkungen

Handle under nitrogen atmosphere and protect from moisture and air.
