A kutatási téma leírása:
In the last decades the development of new heterogeneous catalysts and heterogeneous catalytic methods became a very important branch in the organic chemical results. A number of new catalysts were developed and used successfully in organic syntheses, opening sometimes new horizons in the synthetic methods (e.g. palladium-catalysed C-C coupling reactions). Among the support examined, the mineral based materials have an outstanding importance, since they are not expensive, generally nontoxic, and easy recoverable. The acid-basic properties of these materials may influence the reaction to be catalysed advantageously.
Our research group works on the elaboration of new supported metal catalysts and examines their applicability in different organic syntheses. Recently we used successfully palladium on Mg-Al mixed oxide in different C-C coupling reactions (Heck, Suzuki, Sonogashira coupling), nickel on the same support in the Kumada coupling, and copper on 4 Å molecule sieves support in the A3-coupling and other reactions. The aim of the work is the further development of new catalyst, containing other metals (e.g. Co, Fe, La, as well as mixed metals), and using them in cyclization, C-C coupling and other reactions.
