A review of methods to prepare pyrenes, circulenes, and other condensed acenes. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5Formula: C18H11BrO).

2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.Formula: C18H11BrO
