hydrogenchloride in diethyl ether (Ar); to soln. of Ti complex was added threefold excess of HCl in etherat -78°C, mixt. was slowly warmed up to room temp.; solvent was decanted and residue extd. with pentane, eytt. yielded CpTiCl3, residue was extd. with CH2Cl2, yielding Cp2TiCl2; identification by spectroscopy;

in diethyl ether (Ar); to soln. of Ti complex was added threefold excess of DCl in etherat -78°C, mixt. was slowly warmed up to room temp.; solvent was decanted and residue extd. with pentane, eytt. yielded CpTiCl3, residue was extd. with CH2Cl2, yielding Cp2TiCl2; identification by spectroscopy;
