While (1- and 2-cycloheptatrienyl)phenylcarbonium ions undergo electrocyclizations through the cycloheptatriene forms giving dihydrobenzazulenes, (3-cycloheptatrienyl)diphenylcarbonium ion does through the norcaradiene form. (7-Cycloheptatrienyl)diphenylcarbonium ion undergoes a rearrangement.A possible rationalization is discussed.
