Concept explainers
Interpretation:
Using aniline as a starting material and 2-aminothiazole, the synthesis of sulfathiazole is to be shown and the conversion of sulfathiazole to succinylsulfathiazole is to be provided.
Concept Introduction:
▸ Electrophiles are electron deficient species which has positive or partially positive charge. Lewis acids are electrophiles which accept electron pair.
▸ Nucleophiles are electron rich species which has negative or partially negative charge. Lewis bases are nucleophiles which donate electron pair.
▸ Free radical is an atom, molecule or ion that has an unpaired electron which makes it highly chemically reactive.
▸ Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a functional group is substituted by any other functional group is called substitution reaction.
▸ Elimination reaction: A reaction in which two substituent groups are detached and a double bond is formed is called elimination reaction.
▸ Addition reaction: It is the reaction in which unsaturated bonds are converted to saturated molecules by the addition of molecules.
▸ Aniline and substituted aniline reacts with nitrous acid at low temperature to form benzene diazonium salts.
▸ The reduction of nitro group results in the formation of primary
▸ Electrophiles are electron deficient species which has positive or partially positive charge. Lewis acids are electrophiles which accept electron pair.
▸ Carboxamide undergoes hydrolysis more rapidly than sulfonamide.
▸ The aniline undergoes acetylation to protect the amino group and form acetanilide.
▸ Acetanilide undergoes the electrophilic
▸ Addition of
▸ The sulfathiazole reacts with the succinic anhydride which leads to the formation of final product that is succinylsulfathiazole.
