Regioselective Synthesis of Bicyclic Diselenides by the Reaction of Phosphonium Ylides with Elemental Selenium
摘要:
Selenabicyclo[2.2.1]heptenes reacted with elemental selenium to produce unusual bicyclic diselenides in 30-40% yield. The reaction of phosphonium ylides with excess of elemental selenium also afforded bicyclic diselenides in good yields. The reactions might proceed via biradical intermediates.
