"Advanced" Electrophilic aromatic substitution:


 * Vilsmeier–Haack reaction
 * Instructor says that "in principle thionyl chloride could also react" (without arene, amide would form nitrile, which can still react with arene via the Hoesch reaction)


 * Meisenheimer complex
 * Benzyne mechanism


 * Interconversion of phenyl azide v. phenylhydrazine (starting from aniline and nitrobenzene)
