Reactions of benzene lead to the retention of the aromatic core. Types of Reactions. Electrophilic. substitution. Diazonium. 15-8. Benzene undergoes substitution reactions with electrophiles.. Electrophiles attack benzene by substituting for a hydrogen atom, not addition to the ring.. Under the conditions of this type of reaction, ordinary non-aromatic conjugated polyenes would polymerize rapidly.. Dr. . Sheppard. CHEM . 2412. Summer 2015.

In the last years, the application of computational methodologies in medicinal chemistry field has found an amazing development. In spite of the increasing reliability of computational methodologies, not always the designed leads, once synthesized and screened, are suitable for the chosen biological target. To give another chance to these inactive compounds many structural modification could be carried on such as the introduction of side chains. As recently reported in literature, . In 1825, Michael Faraday isolated a hydrocarbon called benzene, which consists of a six-carbon ring with alternating double bonds and the molecular formula C. 6. H. 6. . . Learning Goal .
