Gattermann reaction

Gattermann reaction

The Gattermann rection, named for the German chemist Ludwig Gattermann, in organic chemistry refers to a reaction of hydrocyanic acid with an aromatic compound, in this case benzene, under catalysis with Friedel-Crafts catalyst (aluminium chloride). [cite journal
author= L. Gattermann, W. Berchelmann
title = Synthese aromatischer Oxyaldehyde
journal = Berichte der deutschen chemischen Gesellschaft
year = 1898
volume = 31
issue = 2
pages = 1765–1769
doi = 10.1002/cber.18980310281
] The reaction is similar to the Friedel-Crafts reaction

It should not confused with the reaction where a diazonium salt is converted to an aryl halide by using copper powder and hydrochloric acid as opposed to using cuprous salt of the halide as in the Sandmeyer reaction. [cite journal
author= L. Gattermann
title = Untersuchungen über Diazoverbindungen
journal = Berichte der deutschen chemischen Gesellschaft
year = 1890
volume = 23
issue = 1
pages = 1218–1228
doi = 10.1002/cber.189002301199
] Although in some articles and books this reaction is also called Gatterman reaction. [cite book | title = Organic Chemistry | author = R. N. Morrison, R. T. Boyd | pages = 869]
