Abstract:N-Alkoxy-N-(4-dimethylaminopyridin-1-ium-1-yl)-substituted ureas, benzamides and N-tert-alkylamines were prepared by the reac tion of the corresponding (N-chloro-N-alkoxy)amino compounds with 4-dimethylaminopyridine. The XRD study of N-alkoxy-N-(4-dimethylaminopyridin-1-ium-1-yl)ureas has revealed the high pyramidality of the central nitrogen atom in O–N–N+ geminal system.
