Gattermann–Koch-szintézis

A Ludwig Gattermann és Julius Arnold Koch német kémikusokról elnevezett Gattermann–Koch-szintézis[1] olyan Friedel–Crafts acilezési reakció, melynek során benzolszármazékból szén-monoxid és sósav hatására Friedel–Crafts-katalizátor, név szerint AlCl3 mellett egy lépésben benzaldehidszármazék keletkezik.[2] Benzaldehid és számos más aromás aldehid is kényelmesen előállítható ezzel a reakcióval. Nyomnyi mennyiségű réz(I)-klorid és cink-klorid jelenléte is szükséges.

A reakcióra példa a toluol p-tolualdehiddé történő átalakítása.[3]
