Catalysts of formula M (UNDER {sub, 4}) {sub, 2} H {sub, 3} Or (M = rare earth cation) and its procedure of synthesis. The compounds object of the patent have been obtained by hidrotermal synthesis by reaction of a mixture of the rare, propilamina Earth and dimetilsulfóxido a salt of, like sulphate source. This mixture is warmed up during days under pressure autogenous. After this time we let cool slowly. When we reached room temperature we abrimos the sterilizer and we filtered obtained products, washing with water first and soon with alcohol. They are its applications in reactions of hydrogenation of olefins, and the group nitro, nitroaromáticos compounds and reactions of sulfide oxidation.
