A FACILE SYNTHESIS OF PALLADIUM CONTAINING METALLODENDRIMER BASED ON DIAZINE AND ITS APPLICATION AS A CATALYST

A palladium containing metallodendrimer has been directly prepared by the reaction of 2,4,6-Triaminopyrimidine (Diazine) with 4-methyl benzoyl chloride using (Ph3P)2PdCl2 in DMF at 70 oC in good yields. The compound was characterized with IR, NMR, Mass and other spectroscopic methods while SEM andEDX showed the surface morphology and the presence of Palladium chloride of the compound. TG and DSC exhibited the good thermal stability of themetallodendrimer. The compound was found to be an effective homogeneous catalyst for the C-C cross-coupling reaction such as Heck and Sonogashira.
