4Methyl-3-penten-2-01 (1) and cyclopentadiene react in an acidic two phase system at 0ยฐC to form allylcyclopentenols 2 and norbornenylcarbinols 4. At 50ยฐC and under similar conditions, 2 as well as 4 are equilibrated to allylcyclopentadienes 3, bicyclic olefins 5 and 6 , and tricyclic ether 7. With
