peculiar vicinaldiamine structure. The first synthesis of this molecule is reported. It features oxidative dimerization of an aci-nitro anion derived from tris(hydroxymethyl)nitromethane and disproportionation catalyst-facilitated hydrogenation of the resulting vicinal tertiary dinitro compound. As the synthesis requires only four steps with no chromatographic separations, it provides a convenient route

Synthesis of 2,3-bis(hydroxymethyl)butane-1,2,3,4-tetraol is of great interest because of its utility as a potential precursor to new dendrimers, in the preparation of unnatural lipids, and in the synthesis of open-framework coordination polymers. Synthesis of this new six-hydroxyl compound is achieved in four steps from commercially available starting materials. In this process, a new olefin-forming

A novel 1,3,2-dioxathiane-2-oxide derivative 5,5'-dinitro-[5,5'-bis(1,3,2-dioxathiane)]2,2'-dioxide was synthesised. Moreover, the molecular structure of the compound was confirmed by the X-ray crystal structure determination.
energetic compounds combining nitro with nitrocarbamate groups were synthesized. The precursors, polynitro alcohols, were obtained by the condensation of the readily available starting material nitromethane with the small aliphatic aldehydes formaldehyde and glyoxal. The conversion into carbamates was achieved with the reactive chlorosulfonyl isocyanate (CSI) and a final nitration yielded the polynitrocarbamates
