Abstract

The carbon-13 nuclear magnetic resonance spectra of l-aryl-3, 3-dialkyl-l-nitrosoureas and related compounds were measured at about-40°C, and their chemical shifts were assigned. The conformations of the N-nitroso compounds having the l-aryl-l-nitrosoureido group were established through comparisons with N-alkyl-N-nitrosoanilines, and the decomposition mechanism of 1-aryl-3, 3-dialkyl-l-nitrosoureas is discussed on the basis of the results.
