Vibrational, conformational and electronic structure investigations of α,α'-dibromo-o-xylene, α,α'-dibromo-m-xylene and α,α'-dibromo-p-xylene.
The Fourier transform infrared (FTIR) and FT-Raman spectra of α,α'-dibromo-o-xylene (DBOX), α,α'-dibromo-m-xylene (DBMX) and α,α'-dibromo-p-xylene (DBPX) of the configuration BrCH(2)C(6)H(4)CH(2)Br have been recorded in the range 4000-400 and 4000-100 cm(-1), respectively. The conformational analysis of these compounds was performed. The complete vibrational assignment and analysis of the funda...
متن کاملSynthesis of 3-deoxy-3,4-didehydro derivatives of 5-O-mycaminosyltylonolide, 5-O-(4-deoxymycaminosyl) tylonolide, and desmycosin.
The 3-deoxy-3,4-didehydro derivatives of 5-O-mycaminosyltylonolide, 5-O-(4-deoxymycaminosyl)tylonolide, and desmycosin have been prepared by treatment of the corresponding 3-O-sulfonyl derivatives with NaI in 2-butanone as the key step. The mechanistic difference in the formation of the 2,3- and 3,4-unsaturated derivatives from the same 3-O-sulfonyl derivative is discussed.

The title compound, [Zn3(C2H5)2(C6H5O3)4]·2C7H8, crystallizes with one complex mol-ecule solvated by two mol-ecules of toluene in the asymmetric unit. The Zn(II) ions are coordinated by two terminal ethyl (Et) groups and four maltolate ligands, which act as μ3- and μ2-bridges. The metal atoms are arranged in an incomplete cubane Zn3O4 core structure, derived from one EtZnO3 tetra-hedron, one Et...
متن کاملPoly[4-(dimethylamino)pyridinium [(μ6-5-carboxybenzene-1,2,4-tricarboxyato-κ6 O 1:O 1′:O 2:O 4:O 4′:O 5)diargentate(I)]]
In the title compound, {(C(7)H(11)N(2))[Ag(2)(C(10)H(3)O(8))]}(n), the polymeric anion consists of two Ag(I) atoms and a Hbtc(3-) ligand (H(4)btc = benzene-1,2,4,5-tetra-carboxylic acid). Each Ag(I) atom is coordinated by four O atoms from three different Hbtc(3-) ligands. The two Ag(I) atoms are bridged by two bidentate carboxyl-ate groups into an Ag(2)O(4) cyclic unit, with an Ag⋯Ag distance ...
متن کاملTernary System Al 2 O 3 – MgO – CaO : Part II , Phase Relationships in the Subsystem Al 2 O 3 – MgAl 2 O 4 – CaAl 4 O 7
Solid-state compatibility and melting relationships in the subsystem Al2O3–MgAl2O4–CaAl4O7 were studied by firing and quenching selected samples located in the isopletal section (CaOzMgO)–Al2O3. The samples then were examined using X-ray diffractomtery, optical microscopy, and scanning and transmission electron microscopies with wavelengthand energy-dispersive spectroscopies, respectively. The ...
