Some d bis-π-cyclopentadienyl titanium complexes with nitrogen or phosphorus ligands
Abstract
Improved routes to the dimer [(π-C5H5)2TiCl]2 are described. With the ligands L = NH3, NH2R, py, Me2PhP, and MePh2P the dimer gives the complexes (π-C5H5)2TiClL. The ligands L2=αα′-bipyridyl, ethylenediamine, or sym-dimethylethylenediamine give the complexes [(π-C5H5)2TiL2]+A– and with L2′= Ph2P·CH2·CH2·PPh2 the binuclear complex [(π-C5H5)2TiCl]2L′2 is isolated.
