Alkynes

Alkynes contain a highly versatile functional group that may be utilized for numerous reactions such as the Sonogashira coupling reaction and related Castro-Stephens reaction; electrophilic additions of hydrogen, halogens, hydrogen halides, or water; metathesis; hydroboration; oxidative cleavage; C–C coupling; and cycloadditions. Terminal alkynes may be transformed into metal acetylides and can then be submitted to nucleophilic substitution with alkyl halides to form new C–C bonds, or submitted to nucleophilic addition such as the Favorskii reaction. Alkyne building blocks with a second functionality are particularly useful in the Huisgen 1,3-dipolar cycloaddition of alkynes to organic azides. The second functional group allows the attachment of a molecule of interest that subsequently can be joined conveniently with the target azide.
