Hydrosilylation of N-allylpyrrolidine and N-allylpiperidine

It was found that the hydrosilylation of N-allylpyrrolidine and N-allylpiperidlne by trialkylsilanes, triethoxysilane, and 3H-heptamethyltrisiloxane in the presence of H₂PtCl₆ · 6H₂O proceeds to form -adducts.Communication XXXII from the series Nitrogen-Containing Organosilicon Compounds.

Synthesis of heterocyclic compounds on the basis of carboxylic acid arylamides

The exchange and cyclization of phenyliminooxalyl chloride with ammonium thiocyanate, sodium azide, aniline, amidoximes, and diphenylthiourea, and with 2-aminopyridine, 2-aminobenzothiazole, and 2-amino- and 2-mercaptobenzimidazole were studied. The cyclization products are derivatives of thiazolidine, imidazo[1,2-a]pyridine, imidazo[2,1-b]benzothiazole, imidazo[1,2-a]benzimidazole, and thiazolo[3,2-a]benzimidazole. A trimer of 1-phenyltetrazole-5-carboxylic acid was obtained when an attempt was made to convert its azide to the corresponding isocyanate.See [1] for communication II.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 471–474, April, 1971.     

New method for synthesis of lamellar compounds of graphite with lithium

Conclusions The stirred reaction of graphite with molten lithium gave compounds of composition C₆Li, C₁₂Li, and C₁₈Li, for which the identity periods and thicknesses of the filled layers were determined.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 3, pp. 671–672, March, 1979.
