The crystal structure of the Cu(II) complex of 1,5-bis-[2-(4`,4`,4`-trifluoro-1`-methyl-3`oxo-but-1`-enylamino)-phenoxy]-3-oxapentane (10) has been elucidated by X-ray crystallography. The results obtained show that the complex 10 consists of two crystallographically independent molecules C26H24CuF6N2O5 (A and B), and the metal atom in the complex 10 has four-coordinated arrangement, as a polyhedron with a distorted square with two nitrogen and two oxygen atoms located in corners. \\\\expert2\\nbo\\Journal of Fluorine Chemistry\\2007, v.128. p.762.pdf |

It is revealed that fluxes and anti-tubercular activity increase, as the length of the chain (spacer) between two ent-beyran skeletons of diesters increases. Computations on the level DFT/PBE explain the dependence of complexes stability on a structure of diterpenoid ligands. The structures of three diesters were established by single crystal X-ray analysis. ?? \\\\Expert2\\nbo\\Journal of Inclusion Phenomena and Macrocyclic Chemistry\\2008, V.60, N1-2, 51.pdf |

M 79 Molecular structures of chalcone podands: A prognosis of photoinduced transformations in the crystals [Text] / I. G. Ovchinnikova, O. V. Fedorova, P. A. Slepukhin, I. A. Litvinov, G. L. Rusinov> // Crystallography Reports. - 2009. - Vol. 54, № 1. - P31-39 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: A series of chalcone podands with the propenone group in the ortho position of the bridging aryl substituent with respect to the oxyethylene fragment is synthesized. The influence of the preorganization of the chalcone podand molecules in crystals on their ability to participate in topochemical reactions is investigated. From analyzing the X-ray structural data, the highest probability of the solid-state photochemical [2 + 2]cycloaddition is predicted for podands with phenyl substituents and the oxyethylene fragment containing two or three oxygen atoms. The X-ray structural data for the chalcone podand C32H26O4 (3a) are as follows: a = 7.904(9) A, b = 14.92(2) A, c = 21.30(3) A, ? = 91.7(1)°, monoclinic system, space group P21/c, Z = 4, V = 2510(5) A3, ? = 1.26 g/cm3, and R = 0.046; C34H30O5 (3b): a = 15.738(9) A, b = 11.889(2) A, c = 15.0830(15) A, ? = 105.47(14)°, monoclinic system, space group C2/c, Z = 4, V = 2720.0(9) A3, ? = 1.266 g/cm3, and R = 0.0418; C32H24N2O8 (4a): a = 17.9416(18) A, b = 10.9703(8) A, c = 41.699(2) A, ? = 105.970(11)°, monoclinic system, space group P21/c, Z = 4, V = 2781.4(5) A3, ? = 1.348 g/cm3, and R = 0.0426; C36H32N2O10 (4c): a = 7.6286(5)A, b = 17.9398(10) A, c = 11.5890(3)A, ? = 95.287(4)°, monoclinic system, space group P21/n, Z = 2, V = 1579.27(14) A3, ? = 1.372 g/cm3, and R = 0.0377; and C28H22O6 (5a): a = 15.6032(10) A, b = 8.1131(5) A, c = 17.7334(11) A, ? = 91.381(5)°, monoclinic system, space group C2/c, Z = 4, V = 2244.2(2) A3, ? = 1.345 g/cm3, and R = 0.0309. |

The reaction of compounds 1a,b with compounds 2 and 3 in the presence of trifluoroacetic acid results in the addition of the dimethylphenoxy group to the unsubstituted C(5) carbon atom of the triazine ring. The reactions of triazinones 6-8 with compounds 1a,b in a mixture of trifluoroacetic acid and organic anhydrides are accompanied by the acylation of the nitrogen atom adjacent to the reaction center and affords bis[(3-R-1-acyl-5-oxo-1,4,5,6-tetrahydro-1,2,4-triazin-6-yl)-2,6-dimethylphenoxy]-3-oxapentane or -3,6-dioxaoctane. The obtained adducts can smoothly be oxidized under mild conditions to form more stable products of nucleophilic hydrogen substitution in the triazine ring.

The adsorption of starting benzaldehydes and ethyl acetoacetate on the surface of copper and aluminum nanooxides resulted in the activation of these molecules and accelerated the Hantzsch reaction. In addition, considerable activation of ammonia and intermediates (chalcone and enamine) on the surface of aluminum nanooxide facilitated an increase in the rate and selectivity of the process. The experimental results were used to develop a one-pot method for the preparation of nifedipine and nitrendipine \\\\Expert2\\nbo\\Kinetics and Catalysis\\2010, v. 51, N 4, p. 566-572.pdf |
