Synthesis of peroxides from β,δ-triketones under heterogeneous conditions
摘要:
Heterogeneous reactions of beta,delta-triketones with ethereal hydrogen peroxide in nonpolar solvents, catalyzed by phosphomolybdic acid, afforded mixtures of stereoisomeric ozonides, tricyclic monoperoxides, and bridged tetraoxanes. The trioxolane ring is formed by the carbonyl groups located in the delta-position with respect to each other.
