Theoretical Advances in Aromatic Nitration

In this paper we want to present together our theoretical findings on aromatic nitration, involving both homocyclic and heterocyclic compounds. Our theoretical proposals have been introduced in recent years via several research communications. These theories convey new concepts in Organic Chemistry, such as Electric Hindrance, Autogenic Electromeric Effect, the formation of Precursor Complexes, as well as, short- and long-distance electric interactions in the reactive intermediates. These concepts explain the regiochemistry and the reaction yields, clearing up some obscurities found in Organic Chemistry. Thus, these theoretical considerations are filling gaps in the theory of supposedly well known chemical reactions, improving and updating the Chemical Education.
