WebJan 14, 2024 · 6. According to me net reaction should be at C X 3 when Reimer-Tiemann reaction is done on indole (see image), since in the resonance structure, negative charge is on this carbon. But, the answer given is on C X 2, and the solution given is. In pyrolle, the most electrophilic site is C X 2. Think in a similar way.

WebReimer-Tiemann reaction. The Reimer-Tiemann reaction is an organic reaction used to convert a phenol to an o-hydroxy benzalde-hyde using chloroform, a base, and acid work-up. The mechanism begins with abstraction of the proton from chloroform with the base to form a trichlorocarbanion which spontaneously loses a chloride ion to form a neutral ... WebThis reaction is called the Reimer-Tiemann reaction. b) In the above image, structure (1) is A and structure (2) is B. We can see that the structure(1) has Oh group directly attached to the aromatic ring creating an " enol" system which shows violet colour with ferric chloride solution while the benzyl alcohol will not show any reaction with the solution.
