Heterogeneous Palladium Catalyst

Pyridinyl functionalized MCM-48-supported Pd-catalyst efficiently (0.013–0.025 mol%) promoted Heck, Suzuki and Sonogashira cross-coupling reactions. Moreover, the catalyst was reused five times without significant loss of its activity.

Sonogashira Reactions

An efficient method is developed for the synthesis of 4-(3-arylprop-2-ynyloxy)-6-methyl-2-(methylthio)pyrimidines via palladium-catalyzed Sonogashira reactions of 4-methyl-2-(methylthio)-6-(prop-2-yn-1-yloxy)pyrimidine with electron-poor aryl iodides in acetonitrile at room temperature. Excellent yields of the products were obtained in reaction times of 9–11 h.
