Selenium-catalyzed Functionalization of Alkynes

Selenium catalysis has become an exciting area in organic synthesis. In various selenium-catalyzed reactions, different substrates have been utilized. However, alkynes as substrates have received much less attention than other substrates such as alkenes although the triple bond of alkynes possesses versatile reactivities. This review summarizes the progress of selenium-catalyzed alkyne functionalization. Selenium catalysis has become an exciting area in organic synthesis.
