Q14. - Organic Chemistry

Question

Question: Identify the product M of the following two-step reaction sequence. M was converted to the hallucinogen LSD (Figure 18.4) in several steps.

Step-by-Step Solution

Answer

 Answers

The product M formed by the two-step reaction is shown below.

Step 1: Halogenation

Halogenation is carried out by treating a carbonyl compound that consists of alpha hydrogen atoms with halogen and in the presence of an acid.

Step 2: Nucleophilic reagents

Reagents, such as ethylamine and methyl mercaptan, are nucleophilic reagents due to the presence of lone pairs over N and S, respectively. They take part in bimolecular nucleophilic substitution reactions. The product obtained from the reaction is a nucleophilic substituted product.

Step 3: The formation of the products in the given reaction

The products formed in the given reaction are shown below.
