Nitration of o-Aminophenol, o-Anisidine, and o-Benzenediazonium Oxide in Sulfuric Acid

Entering into a reaction in the protonated form, o-aminophenol is nitrated in 80% sulfuric acid at the para and ortho positions to the hydroxy group to afford a mixture of 4-nitro- and 6-nitro-2-aminophenol and is nitrated and sulfonated in concentrated sulfuric acid, whereas o-anisidine is nitrated at the para positions in both cases, converting into 4-nitro-2-aminoanisole. After diazotization of o-aminophenol and subsequent nitration of o-benzenediazonium oxide, a mixture of the same derivatives as in diazotization of the nitration products of o-aminophenol is formed, but the 6-nitro isomer prevails.
