dc.description.abstractA number of 4- substituted fluoranthenes have been brominated to give monobromo derivatives. These are:en
dc.description.abstractbromo-4- carboxyfluoranthene, bromo-4- cyanofluoranthene, bromo-4-methoxycarbonylfluoranthene, and bromo-4- nitrofluoranthene.en
dc.description.abstractThe orientation of these compounds has been elucidated and in each case the second substituent has been shown to enter the 12- position. These conclusions have been experimentally correlated with the structure of 4:12 -diacetylfluoranthene. A straightforward synthesis of 6- bromo -2- nitrofluorenone has also been accomplished.en
dc.description.abstractStrong evidence has been produced to show that contrary to previous belief disulphonation in fluoranthene occurs at the 4:12 positions.en
dc.description.abstractThese results have been considered in the light of the electronic theory of aromatic substitution, and an explanation of 4:11 and 4:12 substitution has been proposed. This explanation assumes the alteration in balance of two contributing structures in the fluoranthene molecule.en
