Organic chemistry: Strategies for synthesizing substituted benzenes using electrophilic aromatic substitutions--interconversion of nitro and amino substituents; interconversion of alkanoyl and alkyl substituents, Clemmensen reduction, disadvantages of Friedel-Crafts alkylation (rearrangements and overalkylation); reversible sulfonation as a blocking procedure; moderating the activating power of amino and hydroxy substituents. Arenediazonium salts; Sandmeyer reactions; synthesis of phenol from an arenediazonium salt. Phenyl vs. benzyl; oxidation of benzylic carbons to carboxylic acids with hot potassium permanganate (KMnO4) This is a recording of a tutoring session, posted with the students' permission.
