Abstract

The reactions of Li[C₅H₄(CH₂)₂P(CH₃) ₂] (1) with La(CF₃SO₃)₃ and Y(CF₃SO₃)₃ are described. Three equivalents of 1 reacted with La(CF₃SO₃)₃ under formation of La[C₅H₄-(CH₂)₂P(CH₃) ₂]₃ (2). Two equivalents of 1 with one equivalent of Y(CF₃SO₃)₃ in the presence of LiBr yielded BrY[C₅H₄(CH₂)₂P(CH₃) ₂]₂ (3). Both complexes 2 and 3 have been characterized by X-ray structure analysis. In both cases an intramolecular coordination of the phosphanoethyl chain is established in the solid state by X-ray crystallography as well as in solution by NMR spectroscopy.
