The given azo dye has to be prepared via an azo coupling starting from benzene and isopropyl chloride. Concept Introduction : Azo coupling : Aryldiazonium salts on coupling with an activated aromatic ring give an azo dye which produces a deep color in the final product. This color is due to the extended conjugation in it. This reaction occurs by electrophilic substitution reaction. This method is called an azo coupling. The obtained final compound is known as azo dyes. Friedel-Crafts Alkylation: The Friedel-Crafts alkylation involves the electrophilic substitution of alkyl groups on aromatic rings when arenes are treated with alkyl halides in presence of Lewis acids. This reaction is catalyzed by Lewis acids like anhydrous AlCl 3 , FeX 3, ZnCl 2 , BF 3 etc. To find: Prepare the given azo dye via an azo coupling starting from benzene and isopropyl chloride Apply a retrosynthetic analysis for the given azo dye
