Some Baeyer-Villiger oxidations of ketones with m-chloroperbenzoic acid proceed much faster in the solid state than in solution.Relatively few organic reactions have been carried out in the solid state.1 We have found that some Baeyer-Villiger oxidations of ketones with rn-chloroperbenzoic acid (1) proceed much faster in the solid state than in solution.
Ohne Lösungsmittel, lediglich durch Verreiben der festen Reaktanten in einem Mörser, konnten nicht nur einfache Ketone mit NaBH4 reduziert werden, es gelangen auch regio‐ und enantioselektive Reduktionen, wenn Einschlußkomplexe verwendet wurden. Aus den Ketonen 1 und 3 wurden die als Synthesebausteine interessanten Hydroxyketone 2 bzw. 4 hergestellt.
ChemInform Abstract The oxidation of the ketones (I) and (III) with m-chloroperbenzoic acid, yielding the carboxylates (II) or (IV) and (V), is investigated in the solid state or in solution. In case of the ketones (Ic) -(Ie) and (III), the reaction proceeds much faster in the solid state than in solution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
