The main object of this work was to investigate the reaction of 2-bromo-2-nitro-1, 3-indandione with pyridine in order to elucidate the chemica1 character of the former compound and of the bromine atom in particular. From the previous publications of other workers it is known that the bromine atom is very active in 2-bromo-2-nitro-1, 3-indandione; therefore two possibilities could be foreseen in the interaction of the above named substances: first, the formation of a pyridinium salt with bromine as an anion, and second, the action of 2-bromo-2-nitro-1, 3-indandione as a brominating and an oxidizing agent on pyridine.
