STUDIES OF COMPOUNDS IN THE MENTHANE SERIES. XVIII. VAPOR PHASE ISOMERIZATION OF o-1,4-MENTHADIENE IN THE PRESENCE OF DIATOMACEOUS EARTH

Vapor phase isomerization of o-1,4-menthadiene in the presence of diatomaceous earth results in deprotonation of the 1,2 and 4,5 positions to give an equilibrium mixture of o-menthadienes containing both endo- and exocyclic double bonds; the skeletal rearrangement products, 2-isopropyl-3-ethylidene-1-cyclopentene and 4-isopropyl-3-ethylidene-1-cyclopentene, are also formed. o-Menthadienes also undergo dehydrogenation to give o-cumene, and disproportionation to give a mixture of o-cumene and o-menthenes.The dehydrogenation process predominates as the temperature is increased.
