Reactions of cis-and trans-epoxy derivatives of (+)-3-carene and limonene with aldehydes over askanite-bentonite clay
Volcho,Tatarova,Korchagina,Salakhutdinov,Barkhash
, p. 32 - 39 (2007/10/03)
cis-and trans-Epoxy derivatives of (+)-3-carene, limonene, and dipentene react with aldehydes in the presence of askanite-bentonite clay to give acetals. Hydrolysis of the latter selectively yields the corresponding cis-diols. The relative contribution of intra-and intermolecular processes in the reactions of epoxy derivatives with aldehydes is determined mainly by steric factor. * This study was financially supported by the Russian Foundation for Basic Research (project no. 97-03-32 952a).
Molecular rearrangements of α-(trans)- and β-(cis)-3,4-epoxycaranes in acid media
Polovinka,Korchagina,Gatilov,Vyglazov,Zenkovets,Barkhash
, p. 1283 - 1291 (2007/10/03)
Configuration of the oxirane ring in stereoisomeric 3,4-epoxycaranes affects the direction of their skeletal rearrangements in liquid (HSO3F-SO2FCl) and over solid (TiO2/SO42-) superacids; in the latter case, compounds postulated as intermediates in the liquid-phase process have been isolated.
Catalytic transformations of 3-carene oxide over alumina-rare earth oxide catalysts

Isomerization of 3-carene oxide over binary oxide catalysts like Al2O3-Y2O3, Al2O3-Sm2O3, Al2O3-Eu2O3, Al2O3-Pr6O11 and Al2O3-Nd2O3 at 80 deg C and 110 deg C has been studied. 3,6,6-Trimethylbicyclohexane-3-carboxaldehyde and caranone are the major products formed at 80 deg C.Rise in reaction temperature results in an increase in epoxide transformation and an irregular variation in the yield of products.
Transformations of 3-carene oxide at rhenium-containing catalysts
Manukov, E. N.,Bazhina, G. N.
, p. 106 - 110 (2007/10/02)
The transformations of 3-carene oxide at rhenium-containing catalysts were studied.The introduction of rhenium into the catalytic system significantly increases the reaction rate and leads to the formation of compounds not previously encountered in the products from the isomerization of 3-carene oxide, i.e., 3-carene, 3(10),4-caradiene, 3,3,6-trimethylcycloheptanone, and 3-caren-10-ol.
