Abstract
By reaction of palladium halides with D,L-ethionine (D,L-EthH; molar ratio 1:1) in dichloromethane solutions containing an excess of 2,6-dimethyl-4H-pyran-4-one (DMP) [Pd(D,L-EthH)X2] (X=Cl, Br or 1) complexes have been isolated. When the solvent was benzene [Pd(DL-EthH)X2].DMP adducts were obtained in which the DMP molecule does not bind to the metal. The complexes have been characterized by infrared and nmr (H-1 and C-13) Spectroscopy and by thermogravimetric measurements (TG, DTG and DTA). The importance of DMP in determining the reaction course is discussed.
