synthetische
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.
Allgemeine Beschreibung
Tris(dibenzylideneacetone)dipalladium(0) (Pd₂(dba)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.
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.
