Versuchsvorschrift

Under similar reaction conditions as in Example 5, methylenecyclohexane, methylenecyclopentane, 2-methyl-1-pentene, 2,4,4-trimethyl-2-pentene and 2,3-diphenyl-1-propene underwent the isomerization to the thermodynamically more stable isomers shown in Table 1. The isomerization of 2-methyl-1-pentene afforded only 2-methyl-2-pentene and 4-methyl-2-pentenes were not observed.
