Synthesis of 1,7-bis(4′-aminophenylamido)-m-carborane and 1,7-bis(4′-aminophenylcarboxy)-m-carborane

Conclusion 1,7-Bis(4-aminophenylamido)- and l,7-bis(4-aminophenylcarboxy)-m-carboranes were prepared and characterized.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 12, pp. 2786–2787, December, 1986.     

Condensed imidazo-1,2,4-azines. 12. Synthesis and structure of substituted 5-H-imidazo[1,2-b]-1,2,4-triazepin-4-ones (-thiones)

The synthesis has been effected of new representatives of the imidazo[1,2-b]-1,2,4-triazepin-4-ones (-thiones). It has been shown with the aid of IR and UV spectroscopic and mass spectrometric methods that the lactam (thione) form is the predominant one for the compounds synthesized.For Communication 11, see [1].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 5, pp. 694–699, May, 1985.     

Lactam and acid amide acetals. 71. New synthesis of 3-nitro-6-hydroxyindole derivatives

Previously unknown 3-nitro-6-hydroxyindole derivatives were synthesized by condensation of p-benzoquinone with secondary -nitro enamines.See [1] for Communication 70.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 40–45, January, 1992.     

Synthesis and Physicochemical Study of Solid Complexes of Ti(IV), Zr(IV), and Zn(II) with Chrysin

Previously unknown solid complexes of Ti(IV), Zr(IV), and Zn(II) with chrysin were isolated, identified, and studied by thermogravimetric analysis and by UV-Vis, IR, and NMR spectroscopy.     

Catalytic hydroamination of furfuryl and tetrahydrofurfuryl alcohols with nitriles

Reaction of furfuryl and tetrahydrofurfuryl alcohols with nitriles over copper oxide catalysts under a hydrogen pressure of 15 atm at a temperature of 230C gives N-alkylfurfuryl- (yield 46–50%) and N-alkyl-tetrahydrofurfurylamines (49–53%), and N-alkylpiperidines (28–41%). A reaction mechanism is proposed.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 23–26, January, 1988.
