摘要

3, 6, 9, 12, 15, 18-Hexaphenyl-1, 2, 4, 5, 7, 8, 10, 11, 13, 14, 16, 17-dodecadehydro [18] annulene and related compounds have been synthesized. These compounds were found to be stable both in crystalline forms and chloroform solution at room temperature, to have aromatic character by the existance of a diamagnetic ring current on the basis of the nmr spectral data, and to conform to the D6h-symmetry group.
