Step by step solution
Step-by-Step SolutionStep 1: Reaction of thiols
Thiols can be transformed into disulfides in the presence of halides, such as Br2 or I2 . The transformation of disulfides to thiols can occur by using zinc and HCl as the reagent.
Product of reaction a
The SH- group is a good nucleophile. Thiols can be prepared by the attack of on the alkyl halides. The reaction takes place in a single step by the SN2 mechanism. The product of the reaction can be given as follows.
Product of reaction a
Product of reaction b
The SH- group functions as the nucleophile in this reaction. The attack of the nucleophile, , on the alkyl halides leads to the formation of thiols. This reaction is an SN2 reaction, and it occurs via a single step. The product of the reaction can be given as follows.
Product of reaction b
Product of reaction c
Disulfides are formed by the reaction of grapefruit mercaptan with bromine. The hydrogen atoms are eliminated from SH during the formation of disulfides. The reaction of disulfide with bromine can be given as follows.
Product of reaction c
Product of reaction d
In this reaction, disulfides are converted into thiols on treatment with Zn/HCl. The conversion of disulfides to thiols is a reduction reaction. The reaction of disulfide with Zn/HCl can be given as follows.
Product of reaction d
