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.     

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.     

New approach to the synthesis of 3-amino-1,2-benzothiazine 1,1-dioxides

The possibility of obtaining 3-amino-1,2-benzothiazine 1,1-dioxides by nucleophilic substitution of the chlorine atom in 5-nitro-2-chlorobenzenesulfonamides by carbanions generated from substituted acetonitriles was studied.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 2, pp. 264–266, February, 1992.     

Recyclization of 3-phenacylidene-3,4-dihydro-2H-1,4-benzoxazin-2-one under the influence of o-phenylenediamine
