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 decompositrion 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.
