摘要

Abstract: The two-step reaction sequence of a Stevens rearrangement followed by a Hofmann elimination provides a convenient synthetic route for transforming 2, l l-dithia [3.3] metaparacyclophanes to [2.2] metaparacyclophane-l, 9-dienes. The requisite 2, l l-dithia [3.3] metaparacyclophanes are readily available in good yield by the condensation of m- xylylene dibromides with p-xylylene dimercaptans or, alternatively, by the condensation of ...
