H. Kabashima et al., DOUBLE-BOND ISOMERIZATION OF 5-VINYLBICYCLO[2.2.1]HEPT-2-ENE TO 5-ETHYLIDENEBICYCLO[2.2.1]HEPT-2-ENE OVER ALKALINE-EARTH OXIDES, Reaction kinetics and catalysis letters, 58(2), 1996, pp. 255-259
All the alkaline earth oxides exhibit activities for double bond isome
rization of 5-vinylbicyclo[2.2.1]hept-2-ene (VBH) to 5-ethylidenebicyc
lo[2.2.1]hept-2-ene (EBH) at a reaction temperature of 273 K. The orde
r of the activity on the basis of unit weight of catalyst was CaO > Mg
O > SrO > BaO when compared under optimum pretreatment conditions. The
E/Z ratio in the products is determined by the reaction temperature r
egardless of the type of catalyst; the ratios were 82/18 and 88/12 for
the reaction temperatures of 323 and 273 K, respectively.
