Nitração aromática: substituição eletrofílica ou reação com transferência de elétrons? Aromatic nitration: electrophilic substitution or reaction with electron transfer?
Abstract
Aromatic nitration is one of the most relevant class of reactions in organic chemistry. It has been intensively studied by both experimental, including works in the condensed as well as in the gas phase, and theoretical procedures. However, the published results do not seem to converge to an unique mechanism. Electrophilic substitution and electron transfer, in an exclusive way, are both proposed as the main mechanism for the reaction. We review these proposals and discuss the most recent findings.
