Shtamburg [et al.] // European Chemical Bulletin. – 2016. – Vol. 5, № 4. – P. 142-146.https://repository.kpi.kharkov.ua/handle/KhPI-Press/36906New 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.enN-alkoxy-N-(1-pyridinium)urea salts1-N-alkoxyaminopyridinium saltsN-alkoxy-N-chloroureassynthesisstructureArticle
