Über Chalkogenolate. 128. Untersuchungen über Ester der N-Cyancarbamidsäure. 1. Darstellung und Eigenschaften der Ammoniumsalze von N-Cyancarbamidsäureestern und vom N-Methyl-N-cyancarbamidsäureethylester

On Chalcogenolates. 128. Studies on Esters of N-Cyancarbamic Acid. 1. Synthesis and Properties of Ammonium Salts of N-Cyancarbamic Acid Esters and of the Ethyl Ester of N-Methyl N-Cyancarbamic Acid The reaction of NC? N(CO? OR)₂ with NH₃(g) yields NH₄NC? N? CO? OR], where R = CH₃, C₂H₅, and C₆H₅. NH₄NC? N? CO? OC₂H₅] reacts with H₃CI to form NC? N(CH₃)? CO? OC₂H₅. The called compounds have been studied with chemical and spectroscopic methods.
