Comparison of the behaviour in polar and apolar solvents at various concentrations of the monoaryl carbonyl oxides 1 bearing an electron-withdrawing or an electron-donating group, respectively, on the aryl substituent is reported.The results are consistent with the conversion pathways reported in Scheme 1 and show that the electron-donating group increases the intramolecular oxygen-transfer potential of the system.It is also proposed that under some experimental conditions the carbonyl oxides so substituted mainly isomerize into dioxiranes 11.
Carbonyl Oxide Chemistry. Part 3. Regioselectivity of the First Cycloaddition of Carbonyl Oxides to Phenyl Isocyanate: One-pot Synthesis of 1,2,4-Dioxazolidin-3-ones

, p. 3295 - 3298 (2007/10/02)
Carbonyl oxides 3 react with phenyl isocyanate to give the 1,2,4-dioxazolidin-3-ones 4, providing a potentially useful synthesis of a heterocyclic system which is structurally related to several biologically active products.The crystal structure of the di

, p. 629 - 635 (2007/10/02)
Thermal conversion of the 2,3,7-trioxabicyclohept-5-ene, 2, obtained by dye sensitized photo-oxygenation of the furan 1, is strikingly dependent on the polarity of the solvent.The results are rationalized on the basis of the intermediacy of the pol
Regio- and Stereo-selectivity of the First Cycloaddition of Carbonyl Oxide to Electron-poor Alkenes. Bidirectionality of the 1,3-Dipole

The carbonyl oxide (1), derived from the 2,3,7-trioxabicycloheptene (3) by thermal rearrangement, yields, as major products, methyl 1,2-dioxolane-4-carboxylate (8) and the novel tricyclic biperoxide (4) (whose structure was established by X-ray diffraction), by reaction with methyl acrylate and the acrylate (3) respectively, whereas it yields 5-ethoxy-1,2-dioxolane (9) with ethyl vinyl ether.
Photosensitized Oxidation of Furans. Part 13. Trapping Reactions of the Carbonyl Oxides Obtained from Some 2-Methoxy-5-phenylfurans

, p. 1699 - 1704 (2007/10/02)
The dye-sensitized photo-oxygenation in methanol of the 2-methoxy-5-phenylfurans (1a-c), unsubstituted at C-4 with electron-withdrawing groups, leads to the hemiperacetals (4a-c).The reaction provides the first incontrovertible evidence for carbonyl oxide
