Products of nitration of aromatic and heteroaromatic compounds by some transition-metal nitrato-compounds

Abstract

Compounds of a wide range of aromatic reactivity are nitrated by the nitrato-complexes of zirconium(IV) and iron(III) at room temperature. Product isomer ratios are reported. Studies of the nitration of pyridine with these reagents and with tetranitratotitanium(IV) have established conditions under which either 3- or mainly 4-nitropyridine may be formed. Either 7- or mainly 3-nitroquinoline may be obtained from the nitration of quinoline.
