Summary

Dichlorobis(methylcyclopentadienyl)titanium(IV) reacts with 1,5-diarylthiocarbazones (aryl=phenyl,p-tolyl,o-chlorophenyl orp-chlorophenyl) in 1∶1 and 1∶2 molar ratios in tetrahydrofuran in the presence of triethylamine, to yield [(MeCp)2Ti(HDz)Cl], [(MeCp)2Ti(Dz)] and [(MeCp)2-Ti(HDz)2] (MeCp=methylcyclopentadienyl; HDz− and Dz2− are the mono- and di-anions of a 1,5-diarylthiocarbazone, H2Dz).S-Methyl-1,5-diphenylthiocarbazone and [(MeCp)2TiCl2] react to give [(MeCp)2Ti(MeDz)Cl] and [(MeCp)2Ti(MeDz)2] (MeDz− represents the mono-anion ofS-methyl-1,5-diphenylthiocarbazone, HMeDz) in an excess of triethylamine. These new derivatives have been characterised on the basis of elemental analyses, magnetic moment, electrical conductance, i.r.,1H n.m.r. and electronic spectral studies.
