1276430 Preparation of cyclopentadiene transition metal compounds FARBENFABRIKEN BAYER AG 3 Nov 1970 [26 Nov 1969] 52132/70 Heading C2J A process for the preparation of a mono- or bis-cyclopentadiene metal compound of the formula (R) k MeX m Y n , in which R is cyclopentadiene or its alkyl or aryl substituted derivatives, Me is a transition metal, X is halogen, Y is oxygen, k is 1 or 2, m is 0, 1, 2, 3 or 4, n is 0 or 1 with the proviso that when k is 1, at least one of m and n is other than 0, comprises reacting a trialkylsilyl-cyclopentadiene with a metal halide or metal oxyhalide at - 50 C. to 200 C. in an inert organic solvent. Specified metals are Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Y, Zr, Nb, Mo, Tc, Ru, Pd, La, Hf, Ta, W, Re, Os, Ir, Pt and Ac as well as the elements of the lanthanide and actinide series. The following compounds are prepared in the examples: monocyclopentadiene titanium trichloride, bis-cyclopentadiene zirconium dichloride, monocyclopentadiene zirconium and vanadium trichlorides, and monocyclopentadiene vanadium oxytrichloride
