Is cycloheptatriene aromatic

WebAnswer (1 of 2): No it is not aromatic, because its conjugation ends at CH2. Without continuous conjugation in the ring system, aromaticity is not possible. Cycloheptatrienyl … WebCycloheptatriene has been converted into l -glucose via Pseudomonas cepacia lipase-mediated desymmetrization of a meso -3-O-protected cyclohept-6-ene-1,3,5-triol using isopropenyl acetate as solvent. Cycloheptatriene is oxidized to tropone by hydride transfer to trityl cation. Reduction of tropone with NaBH 4 generates cyclohepta-3,5-dienol.
