Riemer Tiemann Reaction

1. Explain Riemer Tiemann Reaction in Organic Chemistry.

The Riemer-Tiemann reaction in organic chemistry used for the synthesis of ortho-formyl substituted phenols from phenols. It involves the generation of an ortho-formyl substituted phenoxide from a phenol and subsequent reaction with a chloroform (CHCl₃) in the presence of a strong base such as sodium hydroxide (NaOH) or potassium hydroxide (KOH).

2. Why Chloroform is used in Riemer Tiemann Reaction?

The chlorform is used in the chemical reaction because of the presence of (KOH) that undergoes de-hydrohaolgentation (loss of H+ and CI-) to form the dichlorocarbene.

3. Is Riemer-Tiemann Reaction a Electrophilic Substitution?

Yes, the Riemer-Tiemann reaction is an electrophilic substitution.

4. What is the Riemer-Tiemann Reaction on Ether?

This chemical reaction cannot be performed on ethers. It is used to convert phenols to ortho-hydroxy benzaldehydes using chloroform which is a base and an acid workup.

5. What is the Temperature of Riemer Tiemann Reaction?

The reaction is basically carried out on a temperation of 70-105°C.

Riemer Tiemann’s Reaction is named after the pioneering discoveries of the 19th-century chemists Karl Riemer and Ferdinand Tiemann. Reimer-Tiemann reaction is a versatile and important reaction in organic chemistry, which is used for the introduction of carbonyl groups into aromatic compounds, making it a fundamental tool for the synthesis of various valuable organic molecules.

Reimer-Tiemann Reaction can be used to synthesize a variety of ortho-hydroxy benzaldehydes, which are important precursors to a variety of other products, such as pharmaceuticals, dyes, and flavorings. Let’s dig deeper into Riemer Tiemann’s reaction discovered by German scientists and explore its mechanism, applications, and more through this article.
