Abstract

IT has been shown by J. C. Earl1 that the N-nitroso-N-arylglycines, for example, Ph.N (NO).CH2.CO2H, on treatment with acetic anhydride lose a molecule of water, giving monomolecular anhydro derivatives which have been termed ‘sydnones’. The structure tentatively suggested for these compounds contains the fused three- and four-membered ring system (I), and is unacceptable for a number of reasons which need not be enumerated.
