Epoxidation of tetracyclodecene hydrocarbons with the H2O2·CO(NH2)2 adduct in the presence of heteropoly compounds containing rare-earth metal cations

Abstract

Epoxidation of tetracyclododecene bridged hydrocarbons prepared via the [4+2]-condensation of bicyclo[2.2.1]hept-2-ene and its alkyl derivatives with cyclopentadiene in the presence of Н-form of synthetic mordenite has been studied. Phosphorus-molybdenum and phosphorus-tungsten heteropoly compounds doped with Co³⁺, Gd³⁺, Nd³⁺, Ce(4–x)+ (x = 0, 1) cations as well these compounds deposited on highly disperse carbon material have exhibited high activity in epoxidation of the synthesized hydrocarbons under the action of the H₂O₂·CO(NH₂)₂ adduct. Structures of the new bridged polycyclic epoxides have been elucidated by IR as well as ¹Н and ¹³С NMR spectroscopy.
