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. [1] Friedel–Crafts reactions are of two main types: alkylation reactions and acylation reactions. Both proceed by electrophilic aromatic substitution. [2] [3] [4] [5]
James Crafts, the son of Royal Altamont Crafts and Marianne Mason (daughter of Senator Jeremiah Mason), [3] [4] was born in Boston, Massachusetts and graduated from Harvard University in 1858. Although he never received his Ph.D. , he studied chemistry in Germany at the Academy of Mines (1859) of Freiberg , and served as an assistant to Robert ...
This reaction is similar to nucleophilic aliphatic substitution where the reactant is a nucleophile rather than an electrophile. The four possible electrophilic aliphatic substitution reaction mechanisms are S E 1 , S E 2 (front), S E 2 (back) and S E i ( S ubstitution E lectrophilic), which are also similar to the nucleophile counterparts S N ...
Phenethyl alcohol is prepared commercially via two routes. Most common is the Friedel-Crafts reaction between benzene and ethylene oxide in the presence of aluminium trichloride. C 6 H 6 + CH 2 CH 2 O + AlCl 3 → C 6 H 5 CH 2 CH 2 OAlCl 2 + HCl. The reaction affords the aluminium alkoxide that is subsequently hydrolyzed to the desired product.

Friedel–Crafts reaction, a type of organic reaction developed by Charles Friedel and James Crafts in 1877. Friedel's law, named after Georges Friedel, the crystallographer, is a property of Fourier transforms of real functions.
A native of Strasbourg, France, he was a student of Louis Pasteur at the Sorbonne.In 1876, he became a professor of chemistry and mineralogy at the Sorbonne.. Friedel developed the Friedel-Crafts alkylation and acylation reactions with James Crafts in 1877, [2] [3] and attempted to make synthetic diamonds.
2-Acetylfuran was prepared by Ashina in 1914 via the reaction of the methyl Grignard reagent on 2-furonitrile. [3] Modern industrial synthesis generally involves the Friedel–Crafts acylation of furan with acetic anhydride.
