Original language name

Trimethylsilylcyclopentadienes with Polyfluorinated Ponytails and Mono- and Bis(?5-cyclopentadienyl)titanium(IV) Complexes Derived from Them

Original language description

All the cyclopentadienes were found, in analogy with similar known compounds, to be mixtures of isomers between which prototropic and on the NMR time scale fast metallotropic shifts occurred, as confirmed by variable-temperature 1H and 13C NMR. The reaction of 4 with TiCl4 gave Ti(IV) complex [{5-C5H4Si(CH3)2CH2CH2C8F17}TiCl3] (5), whereas the reaction of [(C5H4SiMe3)TiCl3] with lithium salts of 1 and 2 yielded complexes [{5-C5H4Si(CH3)2CH2CH2C8F17}{5-C5H4Si(CH3)3}TiCl2] (6) and [{5-C5H3(Si(CH3)2CH2CH2C8F17)2}{5-C5H4Si(CH3)3}TiCl2] (7), respectively. The results show the applicability of fluorous chemistry methodology in early transition metal organometallic chemistry

Czech name

Trimethylsilylcyklopentadieny s polyfluorovanými ohony and mono- a bis(h5-cyklopentadienyl)titaničité komplexy od nich odvozené

Czech description

V analogii s podobnými známými sloučeninami bylo zjištěno, že všechny cyklopentadieny jsou směsi izomerů, mezi kterými probíhají prototropní a na NMR časové škále rychlé metalotropní posuny, což bylo potvrzeno 1H and 13C NMR spektroskopií za proměnné teploty. Reaction 4 s TiCl4 dává Ti(IV) komplex [{5-C5H4Si(CH3)2CH2CH2C8F17}TiCl3] (5), zatímco reakce [(C5H4SiMe3)TiCl3] s lithnými solemi 1 a 2 poskytla komplexy [{5-C5H4Si(CH3)2CH2CH2C8F17}{5-C5H4Si(CH3)3}TiCl2] (6) and [{5-C5H3(Si(CH3)2CH2CH2C8F17)2}{5-C5H4Si(CH3)3}TiCl2] (7). Výsledky ukazují na aplikovatelnost metodologie fluorové chemie v chemii přechodných kovů z počátku periody
