摘要

Abstract: Stibabenzenes and bismabenzenes are readily prepared by dehydrohalogenation of 1-chlorostibacyclohexa-2, 5-dienes and I-chlorobismacyclohexa-2, 5-dienes, respectively. 4-Alkyl-substituted derivatives 16 and 19 are markedly more stable toward polymerization than the parent compounds. Stibabenzene, bismabenzene, and 4-methylbismabenzene are in mobile equilibrium with their head-to-head Diels-Alder dimers. The'H NMR spectra of ...
