Hydrogen bromide to alkynes

A number of the photoaddition reactions of alkynes are not reactions of the alkyne excited state but involve the formation of free radicals by photocleavage of the other compound. The photochemical a/i//-Markownikoff addition of hydrogen bromide to alkynes (equation 35) under conditions where the ionic addition is very slow is an example of this -. [Pg.19]

Anti-Markovnikov addition of hydrogen bromide to alkynes occurs when peroxides are present in the reaction mixture. These reactions take place through a free-radical mechanism (Section 10.10) ... [Pg.375]
