  Synthesis and structure of [24](2,3,4,5)-thiophenophane (superthiophenophane)

  摘要：

  The synthesis of [2(4)](2,3,4,5)thiophenophane (superthiophenophane) (1), the first 'ultimate' heterophane, was accomplished in five steps from 3,4-bis(chloromethyl)-2,5-dimethylthiophene. In the respective C-13 NMR spectra, the signals due to the thiophene ring carbons of 1 appear at lower field than do those of the carbons of 2,10-dithia[3.2.2.3](2,3,4,5)thiophenophane (5). This shift is elucidated as a compression effect between facial p-orbitals of the thiophene carbons. The UV spectra of the two thiophenophanes are, however, almost identical. The results of X-ray crystallographic analysis show that 1 is a more strained molecule than 5.
