Cyclopentadienyl-Liganden mit hydrophilen tentakeln
摘要:
Cyclopentadienyl ligands bearing hydrophilic tentacles are obtained by treating Cp'SiMe2Cl (CP' = Cp or C5Me4H) with H(OCH2CH2)nOMe (n = 2 or 3) in the presence of pyridine; the products Cp'SiMe2(OCH2CH2)nOMe can be deprotonated by potassium in toluene. Reaction of the potassium salt of CpSiMe2(OCH2CH2)2OMe with Me2SiCl2 yields C5H4(SiMe2Cl)(OCH2CH2)2OMe, which can be treated with H(OCH2CH2)2OMe to give C5H4[(OCH2CH2)2OMe]2.
