Nanoflow microreactor for dramatic increase not only in reactivity but also in selectivity: Baeyer-Villiger oxidation by aqueous hydrogen peroxide using lowest concentration of a fluorous lanthanide catalyst

Not only the reaction rate but also the regioselectivity in the scandium bis(perfluorooctanesulfonyl)amide-catalyzed Baeyer-Villiger reaction is remarkably increased by the development of the fluorous nanoflow microreactor system continuously controlled by the nanofeeder DiNaS (Direct Nanoflow System) even in the lowest concentration of the catalyst (?0.1 mol%). The Baeyer-Villiger reaction completes within few seconds as a contact time in the nanoflow microreactor to give the lactone products with high regioselectivity without hydrolysis.

Oxidation of ketones to esters using a tin substituted zeolite beta

Applicants have developed a process for the oxidation of ketones to esters. The process involves contacting the ketone with hydrogen peroxide and a catalyst at oxidation conditions. The catalyst is a molecular sieve represented by the empirical formula: (MwSnxTiySi1?x?y?zGez)O2 where M is a trivalent metal such as aluminum or boron. These molecular sieves have a microporous three dimensional framework structure of at least SiO2and SnO2tetrahedral units, a crystallographically regular pore system and the characteristic x-ray diffraction pattern of zeolite beta.
