Abstract
A series of mono- and di-substituted cyclopentadienyl Group 4 fluorides [Ti{eta-C(5)H(3)R(R')-1,3}F-n(m)], (n = m = 2 and n = 1, m = 3; R = H or SiMe(3); R' = H, Me or SiMe(3)), [Ti(eta-C(5)Me(5))(2)F-2] and [Zr(eta-C5H5)(2)F-2] have been-prepared via the reaction of the corresponding chlorides with SnMe(3)F. The compounds have been characterized by means of H-1 and F-19 NMR, IR and mass spectroscopy and chemical analyses. The solvent dependence of the reactions using SnMe,F is discussed. To demonstrate the wide applicability of this fluorinating system the acetylacetonatofluoro complex [(acac)(2)(eta-C(5)Me(5))Zr(eta-F)SnMe(3)Cl] has been prepared and its crystal structure determined.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
