Abstract

The oxidation by peracetic acid of 2-amino-3-bromofluorene and 2-amino-3- bromofluorenone, and of 1, 3-dibrorno-2-fluorenamine furnished the corresponding nitro derivatives. In the nitrobromofluorenones the bromine was readily replaced hy amino groups in ethanolic ammonia. Ethanolic potassium hydroxide introduced a hydroxyl group into these compounds, hut in one caw elimination of bromine in the l-position with substitution ...
