| Questions And Answer | Back Directory | [Description]
Tris(dibenzylideneacetone) dipalladium (Tris DBA) is used as catalyst for a wide variety of Pd catalyzed reactions including Suzuki coupling, Heck coupling, Negishi coupling, Carroll reaarangement, Trost asymmetric allylic alkylation, Buchwald-Hartwig amination of acryl halides, fluorination of allylic chlorides, arylation of ketones, carbonylation of 1,1-dichloro-1-alkenes, ?-arylation of carboxylic esters, and conversion of aryl and vinyl triflates to aryl and vinyl halides. It is also involved in the synthesis of azepane. Tris DBA is also a novel inhibitor of N-myristoyltransferase-1 with significant antitumor activity.
| [Uses]
Tris(dibenzylideneacetone)dipalladium is used in the preparation of semiconducting polymers processed from nonchlorinated solvents into high performance thin film transistors. Also used in the synthesis of polymer bulk-heterojunction solar sells as a semiconductor. | [Reactions]
1. Catalyst precursor for conversion of aryl chlorides, triflates, and nonaflates to nitroaromatics.
2. Catalyst for the synthesis of epoxides.
3. Catalytic asymmetric allylic and homoallylic diamination of terminal olefins.
4. Site-selective benzylic sp3 palladium-catalyzed direct arylation.

dark purple solid | [Preparation]
First reported in 1970,Tris(dibenzylideneacetone)dipalladium(0) is prepared from dibenzylideneacetone and sodium tetrachloropalladate. Because it is commonly recrystallized from chloroform, the complex is often supplied as the adduct [Pd2(dba)3·CHCl3].The purity of samples can be variable. | [General Description]
Tris(dibenzylideneacetone)dipalladium(0) (51364-51-3) participates in the synthesis of azepane. Crystal structure of Pd2(dba)3 has been determined by three-dimensional X-ray data. Crystals of Pd2(dba)3 are reported to crystalize in triclinic system. It is widely used Pd(0) source in Pd-mediated transformations. | [reaction suitability]
reagent type: catalyst
reaction type: Cross Couplings | [Structure and conformation]
In [Pd2(dba)3], the pair of Pd atoms are separated by 320 pm but are tied together by dba units.The Pd(0) centres are bound to the alkene parts of the dba ligands. |
