Bis(cyclopentadienyl)zirconium(IV) Schiff base derivatives have been synthesized by treating dichlorobis(cyclopentadienyl)zirconium(IV) (Cp2ZrCl2) with bidentate Schiff bases (SBH) viz., N-salicylidenaniline, N-salicylidene-o-toluidine, N-salicylidene-m-toluidine, N-salicylidene-p-toluidine, and N-(2-hydroxyl-1-naphthyliden)aniline, terdentate Schiff bases (SB′H2) viz., N-(3-oxo-1-methylbutyliden)-o-aminophenol and N-(3-oxo-1-phenylbutyliden)-o-aminophenol; quadridentate Schiff base (SB″H2) N,N′-disalicylidene-o-phenylenediamine, in THF, in the presence of triethylamine at room temperature. The resulting derivatives of the type Cp2Zr(SB)Cl, Cp2Zr(SB)2, Cp2Zr(SB′), Cp2Zr(SB″), and (Cp2ZrCl)SB″ [where [SB]−, [SB′]2−, and [SB″]2−-represent the anion of corresponding Schiff bases SBH, SB′H2, and SB″H2] have been characterised by their elemental analysis and by IR, electronic spectra, electrical conductance and molecular weight determinations.
Die Oximato‐Komplexe (I), (III) und (IV) werden durch die 1:1 ‐ oder 1:2‐molare Umsetzung des Dichloro‐Zr‐Komplexes (II) mit den entsprechenden Oximen dargestellt.
Der Ti‐Komplex (II) reagiert mit zweizähnigen Schiffschen Basen im Verhältnis 1:1 zu den Verbindungen (I) und im Verhältnis 1:2 zu den Produkten (III).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
