9.6 Aromatic Diazonium Salts

9.6 Aromatic Diazonium Salts

• The starting material is amine.
• A nitrosonium ion is formed when these reagents are used to form nitrous acid.
• A diazonium salt is created when primary amines react with a nitrosonium ion.

• We will learn what we can do with aryl diazonium salts.

• We are using copper salts in all of the reactions.
• They allow us to achieve transformations that we could not otherwise achieve with the chemistry we learned in Chapters and 5.
• We didn't see how to install a group on the aromatic ring.
• This is the first way we will do this.

• The chloro group can be converted into the amino group.

• We have seen a few reactions with aryl diazonium salts.
• Instructors will cover more reactions of aryl diazonium salts.
• You should look through your notes to see what you're supposed to do.
• There are more reactions that can be performed with aryl diazonium salts.

• In synthesis problems, these reactions are very useful.
• Problems will combine these reactions with elec trophilic aromatic substitution reactions.
• These problems can be difficult at times.
• There are many such problems in your textbook.

• In order to master these types of problems, you must do two important activities.

• You have to review the principles and reactions from the course.
• You should have a strong command over all of the reactions if you get to a point where you know all of them cold.

• You have to do as many problems as possible.
• Even a very strong grasp of the reactions will be insufficient if you don't get practice.
