Copper (II) phthalocyanine and 2, 9, 16, 23 tetrakis nitro copper (II) phthalocyanine has been synthesized respectively from phthalonitrile and 4-nitro phthalonitrile under solvent-free condition using two different catalysts over nanodimensional zeolites. 4-Nitro phthalonitrile synthesized from phthaimide in three steps. The newly prepared compounds have been characterized by IR, UV-Vis,1H N...

In the title compound, C(15)H(13)NO(3), the dihedral angle between the two aromatic rings is 79.25 (16)°.

ABSTRACT The Diels-Alder reaction between methyl (Z)-2-nitro-3-(4-nitrophenyl)-2-propenoate and cyclopentadiene yields a mixture of carbodiene Diels-Alder adducts. B3LYP/6-31G(d) simulations indicate that the conversion of addends into methyl (1R*,2S*,3S*,4R*)-2-nitro-3-(4-nitrophenyl)-bicyclo[2.2.1]hept-5-ene-2-carboxylate occurs via two-stage heterodiene Diels-Alder reaction and (in a second ...

The central acetyl-acetamide moiety in the title compound, C(14)H(9)N(3)O(6), is buckled [e.g. the C-N-C-O torsion angle is 14.3 (6)°] but the r.m.s. deviation for the five atoms is 0.044 Å. The benzene rings lie on the same side of the central plane, forming dihedral angles of 37.17 (15) and 28.58 (19)° with it. The dihedral angle between the two rings is 17.8 (2)° indicating that the mol-ecul...

A new ligand family based on picoline, bipyridine and terpyridine containing a nitro moiety has been synthesized and its coordination and sensitization ability for lanthanide ions has been studied. Three new complexes were characterized by X-ray single crystal diffraction and all three show uncommon coordination of the nitro moiety to the lanthanide ion. 5cTb, a terpyridine-nitro derivative wit...
