The planar alkoxydiazinoxide fragments are shown to have the Z-configuration and be orthogonal to each other by an x-ray structure study of a series of alkoxydiazinoxides.
The kinetics of the methylation of the N-nitroso-N-methylhydroxylamine sodium salt by dimethyl sulfate in an alkaline buffer solution (pH 9.18) was studied with the use of polarography and UV spectroscopy for analytical control of the process. The reaction has zero order in each of the reagents and is complicated by the parallel alkaline hydrolysis of the dimethyl sulfate. The rate constants of both reactions in the range between 15 and 50/degree/C and the activation parameters were calculated. Both reactions take place by the S/sub N/2 mechanism.
An x-ray diffraction structural investigation of bis(N-oxide-N′-methoxydiazenyl)methane and bis-(N-oxide-N′-methoxydiazenyl)(N″-methyl-N″-nitroaminomethyl)methane showed that each of the alkoxydiazene oxide fragments in both molecules has Z configuration.
Low temperature x-ray structural analysis of N-phenyl-N'-methoxydiazene-N-oxide has revealed that the planar conjugated methoxydiazene oxide fragment exists in a Z-configuration with the phenyl substituent rotated about it by a 26° angle.

By x-ray crystallographic analysis it was confirmed that the product from the methylation of Traube's salt has the methoxyazoxy structure, which is also preserved in the product from its reaction with formaldehyde, i.e., they are in fact bis(methoxy-N,N,O-azoxy)-and bis(methoxy-N,N,0-azoxy)bis(hydroxymethyl)methanes.
The authors incorporate x-ray diffraction analysis, NMR spectroscopy, and quantum mechanical calculations into their investigation and determination of the crystal, molecular, and electronic structure of isomers of the title compound. Data on chemical shift and lattice parameters are included and bond properties based on electron density and distribution and spin hybridization are analyzed.
AbstractThe known compounds (I) possess two highly reactive functionalities: the N‐acetoxymethyl group and the N‐2‐nitroxyethyl group.
