The cooler temperatures were used to reduce the reaction rate and help to avoid over nitration. This can also be proved by evaluating the attack of the benzene ring of methyl benzoate on the electrophililic species and nitric acid.4 The C-OCH3 substituent is a meta-deactivator. This substance is also known as N-phenylacetamide, acetanilide, and acetanil. The ester group is the meta deactivator and the reaction takes place at the meta position because the ortho and para positions are destabilized by adjacent positives charges on the resonance structure.2 The major product of the methyl benzoate nitration is the meta product due to carboxyl and nitro groups both being powerful electron withdrawing groups.
