Many inorganic substrates, including olefins and amines, can be oxidized in the presence of an alkylrhenium oxide of the formula R a Re b O c L d as a catalyst with a peroxy compound, such as hydrogen peroxide. In previously known processes, pure alkylrhenium oxides of the formula R a Re b O c L d are used.n n n According to the invention can be used with the same effectiveness in the oxidation reactions catalyst compositions, as they are obtained from the reaction of a Oxorheniumverbindung the formula ReO m A n with an organylating agent, in particular a Grignard, without the production process comprises a costly sublimation, crystallization or distillation.n n n The invention except oxidation processes, includingnthe epoxidation of olefins and the conversion of secondarynAmines in hydroxylamines, catalyst compositions. |
