Metallorganische verbindungen der lanthanoiden: XX. Cyclopentadienyllutetiumderivate von triphenylmethylenphosphoran

Tricyclopentadienyllutetium tetrahydrofuranate reacts with triphenylmethylenephosphorane with the formation of tricyclopentadienyllutetium triphenylmethylenephosphorane. A lutetium-containing metallacycle, 1,1-diphenyl-3,3-dicyclopentadienyl-1-phospha-3-luteto-indane, is formed by the decomposition of dicyclopentadienyl(methyl)lutetium triphenylmethylenephosphorane, by the reaction of dicyclopentadienylchlorolutetium triphenylmethylenephosphorane with sodium hydride or by the reaction of dicyclopentadienyllutetium chloride with lithium triphenylphosphonium methylide, respectively. The ¹H and ¹³C NMR spectra of the new compounds are discussed.
