A series of hybrid catalysts containing tert-butyldimethylsilyltrifluoro-methanesulfonate (BDMST) or lanthanum triflate (LaT), hex adecyltrimethylammonium bromide and silica were obtained by sol-gel immobilization. The catalysts were characterized by nitrogen adsorption-desorption isotherms at 77 K, TG-DTA, H-1, C-13, and Si-29 solid state MAS-NMR, XRD, TEM, scanning electron microscopy (SEM), XPS and, FT-IR after adsorption of NH3. The catalytic tests were carried out in the reaction of the methyl ester of 1-cyclopentenylacetic acid in various solvents. The results revealed a completely different behavior of the hybrid catalysts compared with catalysts without surfactant or with free tert-butyldimethylsilyltrifluoro-methanesulfonate, or lanthanum triflate, or triflic acid, indicating a behavior for a typical heterogeneous catalyst.
