The nitrophenols also undergo oxidation to a very small extent (less than 1 percent); o-nitrophenol yields traces of nitroquinol, m-nitrophenol, nitroquinol and 4-nitrocatechol and p-nitrophenol, 4-nitrocatechol. This is the 5th installment in the 6 part series where I convert Aspirin to Paracetamol.
