The base-catalyzed intramolecular proton transfer in cycloheptatriene derivatives and propene has been investigated both theoretically and experimentally.A direct 1,3-intramolecular proton shift was observed in cycloheptatriene derivatives, the shift proc

Tricyclo2,6>hex-1(6)-ene (3), benzotricyclo2,7>hepta-1(7),3-diene (4) and tetracyclo2,4.03,5>hept-3-ene (5) were generated as short-lived intermediates by methods, which had proved suc

Under the influence of basic alcohol, 7-phenyl-1,3,5-cycloheptatriene (7c) forms its 1-, 2- and 3-isomers (viz. 1c, 2c and 3c) in parallel reactions, contrary to suggestions made in the literature.The activation parameters for these reactions are given.The difference in behaviour (in isomerization and exchange reactions under basic conditions) between 7-(methoxycarbonyl)-1,3,5-cycloheptatriene (7b) and 7-phenyl-1,3,5-cyclopentatriene (7c) is explained by the weaker electron-attracting properties of the phenyl ring as compared to the methoxycarbonyl substituent.
