Intramolecular Anodic Carbon-Carbon Bond-Forming Reactions of Oxidized Phenol Intermediates Leading to Spirodienones. Structural Effects on Reactivity and Evidence for a Phenoxonium Ion Intermediate
Anodic oxidation of 4-phenylphenol in methanol leads to 4-methoxy-4-phenylcyclohexa-2,5-dienones whereas anodic oxidation of 4-(2-alkenylphenyl)-phenols leads to spirocyclic 2,5-cyclohexadienones in competition with methanol addition to the 4-position.Usi
