The influence of ions on the structure of water

Journal of Structural Chemistry - The main features of the changes produced by ions in water may be summarized as follows. The influence of ions on the structure of the “free” water...     

Influence of alkali metal and ammonium cations on the structure of iron(II) and cobalt(III) hexacyanide complexes encapsulated in faujasite

Changing the cation composition (Na⁺ to K⁺, NH₄ ⁺ Cs⁺) of faujasite with hexacyanoferrate(II) encapsulated in the large pores causes distortion of the octahedral symmetry of the complex.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 30, No. 5, pp. 293–297, September–October, 1994.     

Synthesis of unsaturated esters of pyridine- and quinolinedicarboxylic acids

The divinyl, diallyl, and dipropargyl esters of pyridine-2,4-, pyridine-2,6-, and quinoline-2,4-dicarboxylic acids and the divinyl and dipropargyl esters of pyridine-2,5-dicarboxylic acid have been synthesized.     

Cyclization of o-nitrosoacylbenzenes to anthranils

5-Bromo- and 5-methoxy-3-ethylanthranils, respectively, were obtained by cyclization of o-nitrosopropiophenone under the influence of hydrogen bromide in benzene and hydrogen chloride in methanol. In these reactions, the starting nitroso ketone undergoes redox transformations that also proceed readily in an inert solvent in the absence of any cyclizing reagents.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 7, pp. 886–890, July. 1976.
