yields of the desired products, both mono- and bis-nitration products were formed in good yield by one-pot synthesis using NaNO2 in a mixture of water and acetic acid (10 ∶ 1). The use of X-ray crystallography proved the presence of the nitro-substituted products. An investigation into this mild nitration method revealed that the substitution pattern on the aromatic ring governed the ability of the compounds
