1-Alkoxyamino-4-dimethylaminopyridinium derivatives as new representatives of O–N–N⁺ geminal systems and their structure
(Elsevier Inc., 2012) Shtamburg, V. G.; Tsygankov, A. V.; Shishkin, O. V.; Zubatyuk, R. I.; Shtamburg, V. V.; Gerasimenko, M. V.; Mazepa, A. V.; Kostyanovsky, R. G.
Synthesis and structure of N-alkoxyhydrazines and N-alkoxy-N',N',N'-trialkylhydrazinium salts
(Elsevier Inc., 2013) 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 potassium salt of N-acetylbenzenesulfonylamide. The XRD studies of N,N' bis(methoxycarbonyl)-N,N'-dimethoxyhydrazine, N'-methoxy-N'‑methoxycarbonyl-N-acetylbenzenesulfonylhydrazide and 1,1,1-trimethyl-2-methoxyhydrazinium perchlorate revealed the pyramidal configuration of the central nitrogen atoms in O–N–N geminal system, unusual elongation of N–N+ bond and shortening of N–OMe bond in 1,1,1-trimethyl-2-methoxyhydrazinium perchlorate.
The properties and structure of N-chloro-N-methoxy-4-nitrobenzamide
(Elsevier Inc., 2012) Shtamburg, V. G.; Tsygankov, A. V.; Shishkin, O. V.; Zubatyuk, R. I.; Uspensky, B. V.; Shtamburg, V. V.; Mazepa, A. V.; Kostyanovsky, R. G.
The XRD study of N-chloro-N-methoxy-4-nitrobenzamide revealed the high pyramidality degree of its amide nitrogen atom in O–N–Cl moiety. N-Chloro-N-methoxy-4-nitrobenzamide reacts with AcONa in MeCN selectively forming N-acetoxy-N-methoxy-4-nitrobenzamide, whereas its methanolysis in the presence of AcONa yields N,N' bis(4-nitrobenzoyl)-N,N'-dimethoxyhydrazine.
New approach to N,N-dialkoxy-N'-arylureas and N,N-dialkoxycarbamates
(Elsevier Inc., 2011) Shtamburg, V. G.; Tsygankov, A. V.; Gerasimenko, M. V.; Shishkin, O. V.; Zubatyuk, R. I.; Mazepa, A. V.; Kostyanovsky, R. G.
Methanolysis of N-chloro-N-alkoxy-N'-arylureas in the presence of silver trifluoroacetate gives the corresponding N,N-dialkoxy-N'‑arylureas, whereas N-chloro-N-alkoxycarbamates react with alcohols in the presence of silver trifluoroacetate to afford N,N-dialkoxycarbamates.
Synthesis, structure and properties of N-alkoxy-N-(1-pyridinium)urea salts, N-alkoxy-N-acyloxyureas and N,N-dialkoxyureas
(Elsevier Inc., 2007) Shtamburg, V. G.; Shishkin, O. V.; Zubatyuk, R. I.; Kravchenko, S. V.; Tsygankov, A. V.; Shtamburg, V. V.; Distanov, V. B.; Kostyanovsky, R. G.
N-Alkoxy-N-(1-pyridinium)urea salts 3, 4 have been prepared, the conversions of N-acetoxy-N-methoxyurea 7 into N,N-dimethoxyurea 8 and of N-n-propyloxy-N-(1-pyridinium)-N',N'-dimethylurea chloride 6 into N,N dimethoxy-N',N'-dimethylurea 11 were carried out. A high pyramidality of the amide nitrogen in O–N–X groups [X = N+C5H5, OMe, OC(O)C6H4Cl-p] has been revealed by XRD studies of ureas 3b, 8 and N-p chlorobenzoyloxy-N-n-butyloxyurea 9.
N-Chloro-N-alkoxyureas: synthesis, structure and properties
(Elsevier Inc., 2006) Shtamburg, V. G.; Shishkin, O. V.; Zubatyuk, R. I.; Kravchenko, S. V.; Tsygankov, A. V.; Mazepa, A. V.; Klots, E. A.; Kostyanovsky, R. G.
The XRD studies of N-chloro-N-alkoxyureas 1, 2 have revealed the high pyramidality of the amide nitrogen in the O–N–Cl group caused by nO–s*N–Cl anomeric effect, the other sequence of this effect is anionic lability of the chlorine atom; nucleophilic substitution at the nitrogen depends on the N'-substitutent nature: chlorine atoms in ureas 1 and 5 are replaced by outer nucleophile whereas, under the same conditions, ureas 2–4 undergo cyclization into 1-alkoxybenzimidazolin-2-ones 10–12.
Pyramidal amide nitrogen in N-acyloxy-N-alkoxyureas and N-acyloxy-N-alkoxycarbamates
(Elsevier Inc., 2006) Shishkin, O. V.; Zubatyuk, R. I.; Shtamburg, V. G.; Tsygankov, A. V.; Klots, E. A.; Mazepa, A. V.; Kostyanovsky, R. G.
The XRD studies of N-acyloxy-N-alkoxyamides 1, 2 have revealed a highly pyramidal configuration of amide nitrogen in the O–N–O group.
Geminal systems 64.*N-Alkoxy-N-chloroureas and N,N-dialkoxyureas
(Springer and Business Media, Inc., 2015) 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) bond due to the nO(Alk)*N—Cl anomeric effect. Alcoholysis of N-alkoxy-N-chloro derivatives of urea, N´-arylureas, and carbamates in the presence of silver trifluoroacetate leads to sterically hindered N,N-dialkoxyureas, N,N-dialkoxy-N´-arylureas, and N,N-dialkoxycarbamates, respectively.
Chiral ureas with two electronegative substituents at 1-N: An unusual case of coexisting pyramidal and almost planar 1-N atoms in the same crystal
(Wiley‐Liss, Inc., 2009) Shishkin, O. V.; Shtamburg, V. G.; Zubatyuk, R. I.; Olefir, D. A.; Tsygankov, A. V.; Prosyanik, A. V.; Mazepa, A. V.; Kostyanovsky, R. G.
XRD studies of structure of N‐acetoxy‐N‐methoxyurea and N,N‐bis(methoxycarbonyl)‐N‐methoxyimide have revealed that in N‐methoxy‐N‐X‐ureas (X = OAc, Cl, OMe, N+C5H5) the additional shortening of N–OMe bond took place, which arising from an nO(Me)‐σ*N–X anomeric orbital interaction. XRD studies of N‐chloro‐N‐ethoxyurea crystal have revealed the presence of two kinds of anomeric nitrogen configuration in the O–N–Cl group in the form of a pyramidal configuration and a planar configuration for same 1‐N nitrogen atom. XRD studies of N‐4‐chlorobenzoyloxy‐N‐ethoxyurea have revealed that the degree of pyramidality of the 1‐N nitrogen in N‐aroyloxy‐N‐alkoxyureas is tuned by orientation of benzoyl group with respect to the N–O bond, which in turn depends of size of N‐alkoxy group.
