Chem 334 1nd Edition Lecture 24Outline of Last Lecture I. Acidity and synthesis of aminesOutline of Current Lecture II. Alkylation of AminesIII. Arendiazonium Salt ReactionsCurrent LectureAlkylation of amines:Primary, secondary, and tertiary amines can do SN2 reactions with alkyl halides. Br NH3 NH3 Br-The problem with this is that we end up with a mixture of products from these reactions. To avoid this problem, we use over alkylation as well as some elimination.Alkyl groups are electron donating. Therefore the product formed from these reactions is typically a good nucleophile. We can get a single product from the reaction if we use the amine in excess. Br NH2(excess) NH Arendiazonium Salt reactions: N≡NArendiazonium salts can be synthesized from primary aryl amines using Sodium nitriteThese notes represent a detailed interpretation of the professor’s lecture.
