Versuchsvorschrift

A solution of 2.5 ml (0.027 mol) of oxalyl chloride in 15 ml of anhydrous carbon tetrachloride is poured dropwise into a solution of 3.4 ml (0.027 mol) of tetramethylurea in 10 ml of anhydrous carbon tetrachloride kept stirring under a nitrogen atmosphere. While the stirring is continued, the reaction medium is maintained at reflux until the evolution of carbon dioxide and carbon monoxide gases has ceased. The formamidinium chloride obtained in the form of a white solid is dissolved at 0° C. in 30 ml of anhydrous acetonitrile.
