Synthesis, characterization and styrene polymerization behavior of alkoxysilyl-substituted monocyclopentadienyltitanium(IV) complexes
Popis výsledku v původním jazyce
Trimethylsilylcyclopentadienes bearing alkoxysilyl functionality, C5H4(SiMe3)(SiMe2OR), where R is Me (2), i-Pr (3) and t-Bu (4), were prepared and characterized. Methoxy derivative 2 reacts with TiCl4 giving unstable [Ti(h5-C5H4SiMe2OMe)Cl3] (5), whichis slowly transformed to chlorosilyl complex [Ti(h5- C5H4SiMe2Cl)Cl3] (6) and a mixture of cyclopentadienyltitanium(IV) methoxides on heating. Fully alkoxylated derivatives of the type [Ti(h5-C5H4SiMe2OR)(OR)3] [R = Me (7), i-Pr (8), t-Bu (9)] and {Ti[h5- C5H4SiMe(OMe)2](OMe)3} (10), were synthesized in low-to-moderate yields from respective chlorosilylcyclopentadienyltitanium trichlorides. All prepared alkoxysilyl compounds were characterized by spectroscopic techniques including 29Si NMR. Polymerization activity of 7-10 in the presence of methylaluminoxane was determined and compared with [TiCp(OMe)3] and corresponding trimethylsilylsubstituted compounds [Ti(h5-C5H4SiMe3)(OR)3], where R is Me, i-Pr and t-Bu.
