Some properties of dicyclopentadienylcalcium have been investigated. The compound has been shown to form complexes with nitrogen or oxygen donor ligands of the general formula (C5H5)2CaL2 (where L=pyridine or L2= N,N,N',N'- tetramethylethylenediamine, 2,2'-bipyridine or 1,2-dimethoxyethane). When L2= 1,10-phenanthroline a solvated complex (C5H5)2CaL2· n(tetrahydrofuran) or a complex of composition (C5H5)2Ca(L2)2· n(pyridine), n=0.5-2, is obtained. The 1H NMR and IR spectra of these products have been studied. Dicyclopentadienylcalcium has also been shown to be a useful cyclopentadienylating reagent, which readily forms cyclopentadienyl compounds on reaction with metal halides. © 1973.
