Sur le Mode de Reaction Des Alkylfluorobore BRnF3-n (n = 0,1,2 et 3) Avec l'acetylacetone

Abstract The NMR spectra of alkylfluoroborane BRnF3-n (n = 0, 1, 2, 3) acetylacetone C5H8O2 systems have been studied with a view to rationalizing more accurately their behaviours. At low temperatures, the C5H8O2.BRnF3-n adduct has been characterized; however, when the temperature is increased some chelated compounds appear by elimination of HF (n = 0, 1, 2) or an alcane (n = 3). The disproportionation ability of these systems has been investigated.
