l-Methyl-2, 3-benzocycloalkenylcarbinyl tosylates 5 were synthesized and their solvolytic reactivity wm determined. Neither in acetolysis nor in hydrolysis in 60% acetone was a ring size effect of any significance evidenced. The reactivities mirrored those of the unmethylated analogs 3. Products from 5 were totally rearranged via aryl ring migration indicating that aryl participation was essentially the only solvolysis pathway. The opposing factors in 3 of ...
