Cascade Reactions Initiated by Addition of Se-Centered Radicals to Alkynes

2 Cascade Reactions Initiated by Addition of Se-Centered Radicals to Alkynes 

5 CASCADE REACTIONS INITIATED BY ADDITION OF fflGHER MAIN GROUP (V)-CENTERED RADICALS TO ALKYNES 

Of the higher main group (V) elements, only P-centered radicals have been used in intermolecular radical additions to alkynes, whereas radical reactions with the unpaired electron located at the higher metallic elements arsenic, antimony, and bismuth have not been reported.
