SYNTHESIS AND INFRARED SPECTRA OF GUANYLUREAS

Abstract
When 1-amidino-3-nitrourea is reacted in aqueous solutions of amines, nitrous oxide and carbon dioxide are eliminated and guanylureas are formed, together with disubstituted ureas as by-products. The infrared absorption spectra of some disubstituted ureas and nitrates of guanylureas are discussed with tentative assignment of bands to some groups.
