However, a competitive formation of a benzothiophene side product 1054 was observed which could be suppressed by decorating the alkyne (R 1) with an electron-withdrawing ester. 808. The Friedel–Crafts reactions are a set of reactions developed by Charles Friedel and James Crafts in 1877 to attach substituents to an aromatic ring. Friedel–Crafts reactions are of two main types: alkylation reactions and acylation reactions. Both proceed by electrophilic aromatic substitution.
