Palladium(0)-dibenzylidene acetone complexes Pd(dba)having y/x of 1.5 to 3 are prepared according to the invention at a purity of at least 99.5 wt%. The use of Pd(dba)complexes for determining the stoichiometry thereof by means of elementary analysis is made possible according to the invention. In a method for producing Pd(dba)complexes from a Pd-containing reactant and dibenzylidene acetone (dba) in alcohol, according to the invention, a solution of dba in alcohol pre-heated to over 40°C is first prepared, and then the Pd-containing reactant is added to the pre-heated solution, whereupon the complexes are precipitated using a base. |
