Document Summary
Previous material: (cid:120) aromaticity (cid:120) nucleophilic and radical substitution reactions (cid:120) oxidation of alkylbenzenes (cid:120) preparation and reactions of aryl diazonium salts (14. 7) Oxidation of alkylbenzenes: (cid:120) site of oxidation is benzylic carbon (cid:120) some reactions involve the aromatic ring, other reactions involve the ring as a. Predict the product for the following oxidation reaction: Synthesis of anilines via nitroarenes: (cid:120) first step- nitrate the aromatic system (cid:120) second step reduce the nitro group. Ashley causton 2013 (cid:120) prepared by reaction of aniline with sodium nitrite in the presence of aqueous acid. Propose a mechanism for the diazotization reaction above: Ashley causton 2013 (cid:120) diazonium ions are versatile intermediates for the preparation of ring-substituted arenes. Fill in reagents required for the following transformations: I (cid:120) diazonium salts are valuable synthetic intermediates, they allow: preparation of otherwise inaccessible substitution patterns introduction of substituents such as oh, f, i, and cn on the ring.
