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

The steric effect on the cycloheptatriene (CHT) - norcaradiene (NCD) equilibrium has been studied in simple 7-alkyl-7-cyanocycloheptatrienes, such as 7-ethyl-, 7-benzyl-, 7-isopropyl-, 7-cyclopropenyl-, and 7-tert-butyl-7-cyanocycloheptatrienes.The NCD component increases with bulkiness of the 7-alkyl group in this order, but the cycloheptatriene carrying an extremely bulky 7-tert-butyl group is out of this order.
