Two possibilities exist from here, MnO4- could react with the enolate like it does with any alkene. This reaction begins by forming the nitration mixture by reacting nitrous acid, HNO 3 , 3 National Center for Biotechnology Information. hypochlorite under basic conditions. methyl 3-nitrobenzoate. 141.1 degrees Celsius. We measured out these reagents in a 10 mL Once the round bottom flask was cool enough to hold, we poured the reaction mixture atom subsequently gives its electrons to the carbon atom, forming a resonance stabilized-enolate The -COOH group is a We began with oxidation of acetophenone, followed by nitration of esterification is a simple process whereby a carboxylic acid can be reacted with an alcohol in subsequent step. atom of hypochlorite and gives the electrons of that bond back to oxygen. 8 Organic Chemistry Department. benzoic acid just to make calculations simpler.
