Synthesis of fluoro alkyl substitued pyrrole based rhodium and palladium complexes and investigation of their catalitic activities on hydrogenation reaction

In this study, perfluoroalkyl groups [(CH2)n(CF2)7CF3 n=1,2] substitued pyrrole based tridentate ligands (Heptadecafluorodecyl-pyrolle-2-carbothioat, (L1), heptadecafluorononyl-pyrolle-2-carboxylate, (L2)) and their four different Rh(I) and Pd(II) complexes which are soluble in scCO2 have been synthesized and characterized by FT-IR and NMR spectroscopy. The activity of catalysts have been studied on hydrogenation reaction of olefins have different chemical environment. In hydrogenation reactions, styren, 1-octen, cyclohexene and cinnamaldehyde have been used as substrat and studied with constant temperature and H2 pressure. The experiments which proceed in scCO2 and organic solvents, to showed that the scCO2 can be an alternative media of organic solvents. The experimental results also showed that synthesized catalysts active on hydrogenation four different substrats.
