First metal complexes containing the perfluoroacetylacetonato ligand have been prepared by the reaction of anhydrous Ln(OAc)3 (Ln = Eu, Tb, Tm) with heptafluoroacetylacetone, optionally in the presence of other ligands Ph3PO, bpy, and PyO.
The reactions of N-dichlorophosphoryl-P-trichlorophosphazene (Cl3PNPOCl2) with phenylmagnesium chloride, o-tolylmagnesium chloride, p-tolylmagnesium chloride, p-chlorophenylmagnesium chloride, 2-mesitylmagnesium bromide, and 2-thienyl lithium were studied. The resulting pentaaryl phosphazenes R3PNP(O)R2 were separated by using column chromatography, their structures were defined by IR, elemental analysis

A study of the reactivity of Ph3PNLi towards phosphorus electrophiles allowed us to develop a general method to isolate, or cleanly generate in situ, a broad family of polyphosphinimines displaying PN–P bonds. A preliminary application of this methodology is presented here with the synthesis of various Schwesinger-type bases by a simple new procedure employing Ph3PNLi.
A new procedure for the one-pot synthesis of phosphinimines with functional N-substituents using the alkylation of phosphonium aza-yldiid with a-bromo esters or the direct introduction of phosphorus and sulfur groups.
