(1E,3E,5E)-1-Chloro-3-(p-tolylsulfonyl)-1,3,5-alkatrienes (1) underwent facile ring-closure followed by spontaneous removal of hydrogen chloride to form a benzene ring. This reaction sequence occurred at relatively low temperature.

It was found that (E)-vinylic sulfones preferentially afford (Z)-allylic sulfones as kinetically-controlled products by treatment with a base under mild conditions, while (Z)-vinylic sulfones give (E)-allylic sulfones.Such stereochemical relationship was
