Question

Explain the following name reaction 1.Reimer tieman reaction 2.kolbe's reaction. 3. Williamson reaction

Answer 1

Answer:

1. The Reimer Tiemann reaction is an organic chemical reaction where phenol is converted into an ortho hydroxy benzaldehyde using chloroform, a base, and acid workup. ... This results in a nucleophilic attack on the dichlorocarbene, forming an intermediate dichloromethyl substituted phenol.

2. It is named after the scientist Hermann Kolbe. Kolbe's reaction is a carboxylation chemical reaction. This reaction is preceded by allowing sodium phenoxide to absorb carbon dioxide and then heating this product at a temperature of 125°C under the pressure of several atmospheres of carbon dioxide.

3. The Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol (alkoxide). This reaction was developed by Alexander Williamson in 1850. Typically it involves the reaction of an alkoxide ion with a primary alkyl halide via an SN2 reaction.
