Basicity, Synthesis and Reactions of Amines
Start with the big picture
The lesson connects amine structure with basicity: alkyl groups generally increase electron density at nitrogen, while electron-withdrawing and aromatic substituents can reduce it. It contrasts gas-phase and aqueous basicity orders, where solvation and steric effects change the comparison, and distinguishes aniline from heteroaromatic amines. Synthesis coverage includes reductions, Gabriel synthesis, Hofmann rearrangement, and reductive amination, alongside alkylation and its risk of polyalkylation. The reaction survey introduces acylation, sulfonylation, diazotization, nitrosation, eliminations, oxidation, and electrophilic aromatic substitution. Together, these themes help organize how amine structure influences both preparation and subsequent chemistry.
