✦ Synopsis

Solid superbases with basic strength up to H_G 37 can be prepared by a treatment of the carriers such as g-alumina and MgO successively with alkali metal hydroxide and alkali metal under nitrogen or with cesium acetate followed by calcination at 700-7508C in vacuum. The catalytic activity of such superbases was studied in the double bond isomerization of b-pinene.
