Abstract

Palladium(0)-dibenzylidene acetone complexes Pdx(dba)y, with y/x being from 1.5 to 3, are provided according to the invention at a purity of at least 99.5 wt. %. The use of said Pdx(dba)y complexes according to the invention is for determining their stoichiometry by means of elemental analysis. In the method for the production of Pdx(dba)y complexes from a Pd-containing educt and dibenzylidene acetone (dba) in alcohol, according to the invention a solution of the dba in alcohol pre-heated to more than 40° C. is provided first and then the Pd-containing educt is added to the pre-heated solution upon which the complexes are precipitated by a base.
