Abstract

We discovered that reacting Pd3(μ-OOCMe)3 with two moles of trifluoromethanesulfonic acid (Hotf) and then with four moles of 3,5-dimethylpyrazole (Hdmpz) in acetonitrile and benzene produces, in high yields, [Pd(Hdmpz)4](otf)2 and Pd(Hdmpz)4(HOOCMe)2(otf)2, respectively. Reacting PhenPd(OOCMe)2 with Hotf in MeCN yields PhenPd(NCMe)2(otf)2, where labile acetonitrile molecules are substituted by Hdmpz under mild conditions to form PhenPd(Hdmpz)2(otf)2. The structures of complexes have been solved on the basis of X-ray crystallography data.
