Synthesis of New Nonafulvenes Nonafulvenes 1c and 1m – s are prepared by the following methods: (a) Elimination of AcOH from acetoxyalkyl‐cyclononatetraenes ( Scheme 2 ; 1m ); (b) alkylation of nonafulvenolates ( Scheme 3 ; 1c , 1n ); (c) elimination of alcohol from di‐ and trialkoxymethyl‐cyclononatetraenes ( Scheme 5 ; 1o , 1p , 1q ); (d) deprotonation of intermediary formed formamidiniumcyclononatetraenes ( Scheme 6 ; 1r , 1s ). Scope and limitations of these preparative sequences are discussed and compared with the corresponding pentafulvene syntheses.
