An ESR study of some organic complexes of tetravalent vanadium

ESR results are reported for solutions and glasses containing vanadyl diethyldithiophosphate, vanadyl and vanadium diethyldithiocarbamates, and vanadium butylxanthogenate. Comparison with compounds of known structure gives the structures of these complexes.     

Effectiveness of initiation in the reaction of cumene hydeopeeoxide with paramethoxyphenol

Conclusions It was shown by a study of the kinetics of the oxidation of cumene in the presence of the hyeroperoxide and p-methoxyphenol that in the reaction of the hydroperoxide with p-methoxyphenol, radicals are formed with an efficiency equal to 0.54 (120°).Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 10, pp. 2191–2194, October, 1972.     

Synthesis and some chemical transformations of 1-N-(β-hydroxyethyl)-3,6-dimethyluracil

Conclusions A study was made of the synthesis and some of the chemical transformations of 1-N-(-hydroxyethyl)-3,6-dimethyluracil.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 422–428, February, 1972.     

5,6-Dihydro-4h-imidazole[4,5,1-i,j]quinoline derivatives

2-Alkyl(dialkyl)amino derivatives of I and their respective cyclic ammonium salts were obtained by reaction of the 2-chloro derivative of 5,6-dihydro-4H-imidazole [4,5,1-i,j ]quinoline (I) and its methiodide with amines. The eycloammonium salt was converted into 2-amino(alkylimino)-l,2-dihydro derivatives of 5. Methoxy- and methyl-substituted I readily formed 2-amino derivatives by reaction with sodium amide. Comparison of the UV spectra of the 2-amino derivative of I and its fixed tautomeric form indicates that the 2-amino derivative of I exists primarily in the amino form in dioxane and CC14.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1410–1413, October, 1970.
