N2 - This paper is focused on the characterization and study of the catalytic properties of a natural soil from Etlá, Oaxaca, México. Thus, X-ray diffraction, energy dispersive spectroscopy, scanning electron microscopy, thermal methods, infrared spectroscopy, 27Al and 29Si solid-state NMR spectroscopy and surface adsorption properties (N 2-BET) analyses for the target material were carried out. Additionally, in order to test the potential and effectiveness of this material as Lewis acid catalyst, a set of experiments for the promotion of various 1,3-oxathiolanes as well as ortho and para benzyltoluenes were carried out. It was found that the catalytic activity for these reactions depends on the amount of soil, the reaction time and the pyridine concentration used as competitive inhibitor. Finally, the studies on the characterization and uses of the soil were thought in order to contribute to the aim of the green chemistry, by using and promoting friendly environment natural materials.
