Synthesis and structure of new N-alkoxy-N-(1-pyridinium)urea chlorides
Autor: Shtamburg, V. G., Shtamburg, V. V., Tsygankov, A. V., Anishchenko, A. A., Zubatyuk, R. I., Shishkina, S. V., Mazepa, A. V., Klots, E. A.
New N-[1-(4-amino)pyridinium]-N-methoxyurea chloride, N-[1-(2-amino)pyridinium]-N-methoxyurea chloride and their analogs were synthesized by N-alkoxy-N-chloroureas reaction with the proper pyridines in acetonitrile or ether solution by improved proce

Geminal systems 64.*N-Alkoxy-N-chloroureas and N,N-dialkoxyureas
Autor: Shtamburg, V. G., Kostyanovsky, R. G., Tsygankov, A. V., Shtamburg, V. V., Shishkin, O. V., Zubatyuk, R. I., Mazepa, A. V., Kravchenko, S. V.
Molecular and crystal structures of N-alkoxy-N-chloroureas and N,N-dialkoxyureas were studied together with those of N-alkoxyureas as reference compounds. N-Alkoxy-N-chloroureas were found to have an elongated N—Cl bond and a shortened N—O(Alk) b

Methanolysis of N-acetoxy-N-n-propyloxy-N’,N’-dimethylurea in different conditions
Autor: Shtamburg, V. G., Tsygankov, A. V., Shtamburg, V. V., Anishchenko, A. A., Mazepa, A. V., Kostyanovsky, R. G.
The methanolysis of N-acetoxy-N-n-propyloxy-N’,N’-dimethylurea in the presence of strong acids at room temperatures or in the boiling methanol yields N,N-dimethoxy-N’,N’-dimethylurea as final product. Primarily the nucleophilic substitution a

Alcoholysis of N-acetoxy-N-alkoxycarbamates. Synthesis of NH-N,N-dialkoxyamines from N,N-dialkoxycarbamates
Autor: Shtamburg, V. G., Anishchenko, A. A., Shtamburg, V. V., Tsygankov, A. V., Kostyanovsky, R. G.
The alcoholysis of N-acetoxy-N-alkoxycarbamates by methanol or ethanol at 20 – 40 °C yields N,N-dialkoxycarbamates and acetic acid. At the lower temperature the competitive formation of N,N’-bis(alkoxycarbonyl)-N,N’-bis(alkoxy)hydrazines can o

Synthesis and structure of N-alkoxyhydrazines and N-alkoxy-N',N',N'-trialkylhydrazinium salts
Autor: Shtamburg, V. G., Shishkin, O. V., Zubatyuk, R. I., Shtamburg, V. V., Tsygankov, A. V., Mazepa, A. V., Kadorkina, G. K., Kostyanovsky, R. G.
New types of 1,1,1-trialkyl-2-alkoxyhydrazinium chlorides and N-alkoxyhydrazines were obtained by reactions of N-chloro-N-alkoxyureas with trimethylamine or 1,4-diaza[2.2.2]bicyclooctane and by reactions of methyl N chloro-N-methoxycarbamate with pot
