Sur le Mode de Reaction Des Alkylfluorobore BR_nF_3-n (n = 0,1,2 et 3) Avec l'acetylacetone

Abstract

The NMR spectra of alkylfluoroborane BR_nF_3-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.BR_nF_3-n adduct has been charactérized; 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.
