Aromaticity, the property resulting from cyclic conjugation [1], is an important concept in chemistry and has been subject of debate since the 19th century and is still an attracting considerable interest.Since high stability, low reactivity and sustained induced ring current imply to high aromaticity, therefore this concept is one of … alanzoka resident evil 3
