Synthesis and structural studies on mono- and bis(cyclopentadienyl )titanium(IV)/zirconium(lV) derivatives of ferrocenyl hydrazones

Abstract

The reactions of hydrazones, derived by the condensation of acetylferrocene with different aromatic acid hydrazides (benzoic, 2-chlorobenzoic, nitrobenzoic, methylbenzoic), with mono(cyclopentadienyl)titanium(lV) trichloride and bis(cyclopentadienyl) titanium (IV)lzirconium (IV) dichloride have been studied in anhydrous tetrahydrofuran or dichloromethane in the presence and absence of amine. Tentative structural conclusions are drawn for the reaction products based upon elemental analysis, electrical conductance, magnetic moment and spectral (electronic. infrared and ¹HNMR) data.
