Probably the higher one-electron donor power is responsible for the higher 

Isomerization of Alkenes. - Solid superbasic catalysts show remarkable activity in the isomerization of alkenes. At room temperature in the liquid phase the double-bond shift in pent-l-ene and hex-l-ene, and the isomerization of the initially formed 2-alkenes takes place. The highest activity in both types of isomerization is shown by catalysts that have been prepared by deposition of alkali metal by evaporation on MgO calcined below 973 K. In this case the isomerization proceeds on very strong superbasic centres. On MgO-alkali metal calcined at temperatures above 973 K, one-electron donor centres prevail this system causes double bond shift only (Table 7). The superbasic systems are also active in the isomerization of ( )-pent-2-ene to the mixture of (Z)-pent-2-ene and pent-l-ene. The systems for which one-electron donor character prevails are completely inactive in this transformation.
