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.
合成了3,6,9,12,15,18-六苯基-1,2,4,5,7,8,10,11,13,14,16,17-十二烷基氢化[18]环戊烯和相关化合物。发现这些化合物是稳定的无论是在结晶形式,并在室温氯仿溶液,通过NMR谱数据的基础上形成的反磁性环电流是否存在等具有芳香性,和以符合d 6H -symmetry基。
