Topological Analysis of the Experimental Electron Density of Diisocyanomethane at 115 K
Autor: Jürgen Buschmann, Genivaldo Perpetuo, Matthias Röttger, Dieter Lentz, Tibor Koritsanszky, Peter Luger
Publikováno v: Chemistry - A European Journal. 5:3413-3420
The electron density distribution of diisocyanomethane (see picture) is obtained from single-crystal X-ray diffraction data and by ab initio calculations. Multipole models with different restraints are applied to judge the physical significance of th

Studies on the reactivity and structure of phenyl 7-fluoro-4-chromone-3-sulfonate
Autor: Peter Luger, Genivaldo Perpetuo, Werner Löwe, Susan Bischoff, Manuela Weber
Publikováno v: Journal of Heterocyclic Chemistry. 32:249-254
The new, fluorinated benzoxathiinopyrazole 4 and the hitherto unknown fluorinated benzoxathiinodihydropyridine 5 can be produced by reacting the title compound 1 with cyanoacetic hydrazide (3) in the presence of sodium acetate. The structures of the
