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.

Abstract The infrared spectra of five 3,5-dialkyl phenols, six 2-allyl-3,5-dialkyl phenols, and five 4-allyl-3,5-dialkyl phenols are presented. The characteristic infrared absorption frequencies are tabulated in correlation charts. The hyperconjugation and mass effects of substituent groups are discussed.

Infrared absorption spectra of N-substituted derivatives of 2,4-dinitro- and 2,6-dinitroanilines have been measured and interpreted from the point of view of bond and sterical interactions of the substituted amino groups with the both nitro groups.
