The synthesis and transformations of alkynes have held an important position in the field of organic synthesis. How to rapidly introduce alkynyl into organic molecules has been of great interest. Photoredox catalysis has been widely used in organic synthesis because it can generate high reactive free radical intermediates under mild conditions using green and clean energy. Visible light photocatalytic alkynylation has flourished in the last decade, which is believed to be a significant complement to the classic transition-metal-catalyzed Sonogashira reaction. This alkynylation could take place via in situ generated copper acetylide complex from terminal alkynes and copper, which also occurs through alkynyl radical species or radical addition elimination of non-terminal alkynes. Moreover, it was a good supplement to Sonogashira reaction that various radical precursors could be applied to alkynylation by visible-light photoredox catalysis. Based on the type of bonding of alkynylation, the research progress of alkynylation reactions by visible-light photoredox catalysis is reviewed, and the future development of this field is prospected.

Key words: alkynylation, radicals, photoredox, Sonogashira coupling
