Friedel–Crafts alkylations can be reversible. Although this is usually undesirable it can be exploited; for instance by facilitating transalkylation reactions. [10] 1,3-Diisopropylbenzene is produced via transalkylation, a special form of Friedel–Crafts alkylation. It also allows alkyl chains to be added reversibly as protecting groups.
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 ...
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.
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.

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.
English: This is a diagram showing the reaction scheme of the Friedel–Crafts alkylation of benzene. The drawing was done in ACD/ChemSketch v12.01 (using standard ACS structure drawing style) and exported as a Windows Metafile (WMF).
