Від 2018 року кафедра має назву "Органічна хімія, біохімія, лакофарбові матеріали та покриття". Кафедра створена шляхом об’єднання кафедр "Органічна хімія, біохімія та мікробіологія" та "Технологія полімерних композиційних матеріалів та покриттів" (НАКАЗ № 567 ОД від 12.11.2018 року).

Кафедра "Органічна хімія, біохімія та мікробіологія" (від 2005 року). Кафедра "Лакофарбові матеріали і покриття" була організована у 1944 році в Харківському хіміко–технологічному інституті ім. С.М. Кірова.

Кафедра входить до складу Навчально-наукового інституту хімічних технологій та інженерії Національного технічного університету "Харківський політехнічний інститут".

У складі науково-педагогічного колективу кафедри працюють: 3 доктора та 3 кандидата хімічних наук; 1 співробітник має звання професора, 3 – доцента.

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.
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.
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.
Synthesis and structure of new N-alkoxy-N-(1-pyridinium)urea chlorides
(Deuton-X Ltd., 2016) 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 procedure. XRD study of N-[1-(4-amino)pyridinium]-N-methoxyurea and N-[1-(2 amino)pyridinium]-N-methoxyurea revealed the elongation of N-N+ bonds and some shortening of MeO-N bonds, qunonoid deformation of pyridine rings compare to it unsubstituted analog. The substantial pyramidality of central nitrogen atom in O-N-N+ moiety and N-C carbamoyl bonds difference were established too. The structure summary of N-alkoxy-N-(1-pyridinium)ureas salts and other derivatives of 1-(N-alkoxyamino)pyridinium salts has been done.
Alcoholysis of N-acetoxy-N-alkoxycarbamates. Synthesis of NH-N,N-dialkoxyamines from N,N-dialkoxycarbamates
(Deuton-X Ltd., 2014) 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 occur. The alkaline hydrolysis of N,N-dialkoxycarbamates yields NH-N,N-dialkoxyamines.
Methanolysis of N-acetoxy-N-n-propyloxy-N’,N’-dimethylurea in different conditions
(Deuton-X Ltd., 2014) 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 acetoxy group at nitrogen on methoxy group arises. At second stage the transesterification of N,N-dialkoxyamino group of formed N-methoxy-N-n-propyloxy-N’,N’-dimethylurea take place.
