WebNov 8, 2024 · Gattermann-koch reaction is formylation to the benzene nucleus i.e., introduction of -CHO group while Friedel- Crafts acylation reaction is the introduction of RCO-group in the benzene ring.So, Gattermann - Koch reaction can be considered similar to Friedel-Crafts acylation reaction. WebThe formylation of a phenol 1 with chloroform in alkaline solution is called the Reimer-Tiemann reaction. It leads preferentially to formation of an ortho- formylated phenol —e.g. salicylic aldehyde 2 —while with other formylation reactions, e.g. the Gattermann reaction, the corresponding /jara- formyl derivative is obtained as a major product.
