Tetrabenzo[a,c,g,i]fluorenylkomplexe des Titans: Synthese und Anwendungen

Within the scope of this thesis an array of different tetrabenzo[a,c,g,i]fluorenyltitanium complexes were synthesized and fully characterized starting from the benzofused fluorene derivative tetrabenzo[a,c,g,i]fluorene. By reacting the lithium salt [Tbf][Li(THF)4] with chlorotitanium alkoxides and -phenoxides, tetrabenzo[a,c,g,i]fluorenyltitanium complexes of the general formula [(?5-Tbf)TiClx(OiPr)] (x = Cl, OiPr) and [(?5-Tbf)Ti(OAr)] (Ar = C6H5, 4 MeC6H5, 4 tBuC6H5) could be obtained. Furthermore, the TbfTi-complexes [(?5 Tbf)TiCl2(THF)] and [(?5-Tbf)TiCl3] were synthesized, whereupon the titanium(III) complex [(?5 Tbf)TiCl2(THF)] was reacted with radicals to give the compounds [(?5 Tbf)TiCl2TEMPO] and [(?5 Tbf)TiCl2(OtBu)], and the titanium(IV)-complex [(?5 Tbf)TiCl3] was reacted with an array of lithiumphenoxides to form monophenoxide complexes of the general formula [(?5-Tbf)TiCl2(OAr)] (Ar = 4-tBuC6H4, 2,6-Me2C6H3, 2,4,6-Me3C6H2, 2,6-iPr2C6H3, 2,6-Ph2C6H3). Selected compounds were scrutinized as regards their polymerization properties of styrene and ethylene.
