GENERATION AND NOTABLE POSITION DEPENDENT ELECTROCYCLIZATION OF CYCLOHEPTATRIENYLPHENYLCARBONIUM IONS - ELECTROCYCLIZATION OF A NORCARADIENE

Mizumoto, Kiyoharu,Okada, Keiji,Oda, Masaji

, p. 2999 - 3002 (2007/10/02)

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.
