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

摘要

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 De-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 center dot CO(NH2)(2) adduct. Structures of the new bridged polycyclic epoxides have been elucidated by IR as well as (1)De and D-13 NMR spectroscopy.
