1,1,1,4,5,5,5-Heptafluoro-4-(trifluoromethyl)-2,3-pentanedione, a Potent Reagent for the Synthesis of Cyclic λ 5 σ 5 Phosphoranes.

-Title compound (II) is employed for the convenient and high-yielding synthesis of cyclic phosphoranes (III). No interaction of the diketone (II) with the isocyanato group in (Ib) or (Ic) is observed, as known for the corresponding reaction with hexafluoroacetone.
