WebOverview of Alkylation Of Alkynes. Alkylation of alkynes happens when an alkyl atom replaces an H-atom in the alkyne compound. When there is the presence of a C-C triple bond in an unsaturated hydrocarbon, then such a compound is called alkynes. When an alkyl group is transferred from one molecule to a different molecule, it is called alkylation. WebJun 21, 2024 · Friedel-Crafts Alkylation. Friedel-Crafts Alkylation was first discovered by French scientist Charles Friedel and his partner, American scientist James Crafts, in 1877. This reaction allowed for the formation of alkyl benzenes from alkyl halides, but was plagued with unwanted supplemental activity that reduced its effectiveness.
