Nitration

A process for preparing a nitrated compound, comprising the step of

• reacting a compound (A) having at least one aromatic or heteroaromatic ring optionally substituted by one or more organic residues R,
• wherein the organic residue R is selected from the group consisting of fluoro, chloro, bromo, iodo, amino, cyano, hydroxy, nitro, C1-12 alkyl, C2-15 alkenyl, C2-15 alkynyl, C3-15 cycloalkyl, C3-15 cycloalkenyl, cycloalkynyl, C3-5 alkylene, C3-5 cycloalkylene, C3-5 alkenylene, C3-5 alkynylene, halo-C1-6 alkyl, hydroxy-C1-6 alkyl, halo-C3-15 cycloalkyl, C1-10 alkoxy, C3-5 cycloalkoxy, alkylenedioxy, C1-6 acyl, C3-6 cycloacyl, C1-6 acyloxy, C3-6 cycloacyloxy, arylalkyl, heteroarylalkyl, aryl, and heteroaryl group, and where the organic residue R may optionally form an annealed ring system with other rings selected from cycloalkyl, aryl, and heteroaryl rings, and
• wherein the heteroaromatic ring includes at least one heteroatom selected from the group consisting of oxygen, sulfur, phosphor, selenium and nitrogen,
• with a compound of formula (I)
• wherein Y is selected from the group consisting of hydrogen and nitro.
