摘要：

Stable carbocation, bis(3-methyl-1-azulenyl)(1-naphthyl)methyl hexafluorophosphate was synthesized by the hydride abstraction reaction of the corresponding hydrocarbon. The cation showed extremely high stability with pK(R)+ value (11.0). The low temperature H-1 NMR spectra showed that the flipping ring was controlled by 1-naphthyl group.
