THE STRUCTURES OF NITROGUANIDINE AND ITS DERIVATIVES

Abstract
The ultraviolet absorption spectra of a number of derivatives of nitroguanidine were determined. An analysis of the effects of substituents on the absorption spectrum of nitroguanidine has led to the conclusion that it exists as a resonance hybrid of several structures including (a) and (b).[Formula: see text]The bearing of these structures on the nomenclature of nitroguanidine and its derivatives is discussed. Also the structures of some of the derivatives of nitroguanidine have been interpreted from their absorption spectra.
