Adducts of tungsten oxide tetrafluoride with 1,8 - naphthyridine and 2,7-dimethyl - 1,8- naphthyridine : preparation and characterization of WOF4.napy and WOF4.dmnapy

Autor: R. Bougon, L. Arnaudet, Buu Ban, W.C. Kaska, Monique Lance

Publikováno v: Journal of Fluorine Chemistry. 53:171-180

The adducts WOF4.napy and WOF4.dmnapy were prepared from the reaction of WOF4 with 1,8-naphthyridine (napy) and 2,7-dimethyl-1,8-naphthyridine (dmnapy) in dichloromethane. Both adducts were characterized by elemental analysis, X-Ray powder data and i

NMR Investigation of the interaction between monodentate and bidentate nitrogen bases and tungsten(VI) fluoride and oxide fluorides

Autor: R. Bougon, L. Arnaudet, Buu Ban

Publikováno v: Journal of Fluorine Chemistry. 58:294

NMR spectroscopy proved to be an invaluable tool to study the interaction between monodentate and bidentate nitrogen bases and tungsten(VI) fluoride and oxide fluorides in solution. 1 H, 19 F, and 13 C spectra including 2D COSY experiments were used
