New Titanocene Derivatives with Thiocresolate LigandsOn reaction of titanocene dichloride (Cp2TiCl2; Cp = η5-C5H5) with NaSC6H4CH3-o or LiSC6H4CH3-p in toluene/benzene or in pure benzene at room temperature, one chloride ligand is substituted to give Cp2TiCl(SC6H4CH3-o) (I) or Cp2TiCl(SC6H4CH3-p) (II) respectively. Analogously, from Cp2Ti(Cl)CH3 Cp2TiCH3(SC6H4CH3-o) (III) or Cp2TiCH3(SC6H4CH3-p) (IV) is formed. By, substitution of both chloride ligands, the bis(thiocresolato) complexes Cp2Ti(SC6H4CH3-o)2 (V) Cp2Ti(SC6H4CH3-m)2 (VI) and Cp2Ti(SC6H4CH3-p)2 (VII) could be prepared from the corresponding thiocresols in ether using triethylamine as supporting base. The substances were characterized by i.r., 1H n.m.r., and mass spectra.
Notes:
Titanocen-dichlorid (Cp2TiCl2; Cp = η5-C5H5) reagiert mit NaSC6H4CH3-o oder LiSC6H4CH3-p in Toluol/Benzol oder reinem Benzol bei Raumtemperatur unter Substitution eines Chlorid-Liganden zu Cp2TiCl(SC6H4CH3-o) (I) bzw. Cp2TiCl(SC6H4CH3-p) (II). In analoger Reaktionsführung bildet sich aus Cp2Ti(Cl)CH3 Cp2TiCH3(SC6H4CH3-o) (III) bzw. Cp2TiCH3(SC6H4CH3-p) (IV). Die unter Substitution beider Chlorid-Liganden erhaltenen Bis(thiokresolato)-Komplexe Cp2Ti(SC6H4CH3-o)2 (V), Cp2Ti(SC6H4CH3-m)2 (VI) und Cp2Ti(SC6H4CH3-p)2 (VII) konnten aus den entsprechenden Thiokresolen mit Triethylamin als Hilfsbase in Ether dargestellt werden. Alle Substanzen wurden IR-, 1H-NMR- sowie massenspektrometrisch charakterisiert.
