(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.

The radical chain addition of tosyl iodide to some alkenes has been studied.The reaction was carried out at room temperature under visible light, giving the usual high yields of β-iodo sulfones.These adducts were transformed into the corresponding unsatur

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
