Cycloheptatriene ion

WebFeb 13, 2024 · This ion is predicted to be aromatic by Hückel's rule. In 1902, Norris and Kehrman independently discovered that colorless triphenylmethanol gives deep-yellow solutions in concentrated sulfuric acid. Triphenylmethyl chloride similarly formed orange complexes with aluminium and tin chlorides. 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.
