REACTIONS OF [CP2MCL2] (M = TI OR ZR AND CP = ETA-5-C5H5) WITH MULTIDENTATE LIGANDS AND THE SYNTHESIS OF NEW CYCLOPENTADIENYL DERIVATIVES OF TITANIUM AND ZIRCONIUM

The reactions of the dibasic tridentate hydrazones H2L1, H2L2, and H2L3; benzothiazolines HL4 and HL6; 1,2-di(o-aminophenylthio) ethane L8 and a dibasic hexadentate Schiff base H2L9 with [Cp2TiCl2] and [Cp2ZrCl2] are described. The reactions of [TiCpClL5], synthesised ln this study, with MeSH, SiMe3(NMe2), Me3SiC = CPh, Na[FeCp(CO)2], and SnCl4 are also described. Structures for the compounds are proposed on the basis of elemental analyses, molar conductances, molecular weights, and i.r. uv-visible, H-1 n.m.r. spectroscopic data.
