Novel reaction of selenobenzophenones with alkyllithiums leading to symmetrical olefins

The reaction of selenobenzophenones with alkyllithiums or Grignard Reagents exclusively affords symmetrical tetraarylethylenes as selenophilic products. The reaction might proceed through episelenide (selenirane) intermediates.

Isolation and Reaction of Selenobenzophenones

4,4'-Dimethoxy- and 4,4'-dimethylselenobenzophenones could be isolated in moderate yields by the reaction of the corresponding ylides with selenium.Their spectral data are described.The oxidation of these compounds with mCPBA afforded the corresponding benzophenones in good yields.Attempted isolation of unsubstituted selenobenzophenone afforded only its dimer.
