Possibility of the rearrangement of bis-silicon-containing mercaptals to ethers of dithioethylene glycol

Conclusions A study was made of the PMR spectra of some symmetrical organosilicon mercaptals and dithioethylene glycol ethers; their isomerization was not observed.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 11, pp. 2562–2565, November, 1970.     

Order of addition of hydrosilanes to 1-butyn-3-one and 1-butyn-3-ol in the presence of Speier's catalyst

Conclusions The addition of methyldiethylsilane and triethylsilane to 1-butyn-3-ol and 1-butyn-3-one in the presence of Speier's catalyst is nonselective and, depending on the reaction conditions, proceeds both according to and contrary to the Farmer rule.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 839–843, April, 1968.The authors express their gratitude to V. V. Keiko for studying the products by the GLC method.     

Stability and catalytic activity of various cobalt (II)-cyanide complexes in water-monoethanolamine solutions

Stability constants of mono-, di-, tri-, tetra- and pentacyanocobaltate in water-monoethanolamine solution have been calculated. Concentration distributions of these complexes depending on the cyanide to cobalt ratio and rate constants for their isotope exchange in mixed water-monoethanolamine solutions have been determined.

Reaction of phenoxyacetylene with triorganosilanes

Conclusions The addition of trialkylsilanes to phenoxyacetylene in the presence of chlorplatinic acid proceeds stereospecifically at the triple bond, primarily according to the Farmer rule.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 11, pp. 2599–2601, November, 1969.     

Catalytic activity of rhodium-indigo sulfonates in hydrogen-water isotope exchange

Rhodium indigo sulfonate complexes are effective catalysts of isotope exchange between hydrogen and water. A study has been made of the transformation of initial complexes into catalytically active forms. Kinetic regularities of isotope exchange and an equation for the reaction rate have been obtained.

Mineralization of Detoxification Products of Yperite-Lewisite Mixture

The mineralization of the products of detoxification (neutralization) of yperite-lewisite mixture by electrochemical oxidation was studied. A procedure for separation of potassium salts and arsenic compounds by electrocoagulation was developed. A possibility of using the resulting potassium salts as fertilizers for agriculture was discussed.
