Reimer-Tiemann reaction

In the Reimer-Tiemann reaction dichlorocarbene reacts with phenol to salicylaldehyde.

Dichlorocarbene also features in the Reimer-Tiemann reaction.

The Reimer-Tiemann reaction is a chemical reaction used for the ortho-formylation of phenols.

Reimer-Tiemann reaction.

Salicylaldehyde is prepared from phenol and chloroform by heating with sodium hydroxide or potassium hydroxide in a Reimer-Tiemann reaction:

This reagent affects ortho-formylation of activated aromatic rings such as phenols, producing aryl aldehydes in a reaction known as the Reimer-Tiemann reaction.

The vanillin plant Holzminden was not very successful before Karl Ludwig Reimer discovered the Reimer-Tiemann reaction which opened an alternative synthesis route to vanillin.

The Reimer-Tiemann reaction discovered by Karl Ludwig Reimer opened an alternative path to vanillin and Reimer joined the company which was renamed to Haarmann & Raimer.

Other reactions that follow an electrophilic aromatic substitution pattern are a group of aromatic formylation reactions including the Vilsmeier-Haack reaction, the Gattermann Koch reaction and the Reimer-Tiemann reaction.
