General Description

Tris(dibenzylideneacetone)dipalladium, CAS 60748-47-2, is insoluble in water, slightly soluble in dichloromethane and benzene. It is stable in the air, but its solution can be slowly decomposed. Tris(dibenzylideneacetone)dipalladium can be applied in coupling reaction, such as Suzuki, Kumada, Negishi, Buchwald and so on. Besides, Tris(dibenzylideneacetone)dipalladium, has certain irritations, so operators are recommended to wear suitable protective clothing, gloves and eyeshields. This product should be kept in cool and dry conditions, avoiding strong light.

Application as a Reagent

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.
