Boron trifluoride as an efficient catalyst for the selective synthesis of tricyclic monoperoxides from ??,??-triketones and H

摘要

Boron trifluoride was found to serve as an efficient catalyst for the reaction of ??,??-triketones with Hroducing tricyclic monoperoxides in yields from 48-93%. BFacts simultaneously as a catalyst and co-solvent. The synthesis can be scaled up to tens of grams. The resulting peroxides can be easily isolated from the reaction mixture by column chromatography. ? Georg Thieme Verlag Stuttgart New York.
