  Aqueous chemistry of the five-coordinate zirconocene dichloride PhP(CH2CH2–η5-C5H4)2ZrCl2: X-ray structure of the sulfato complex PhP(CH2CH2–η5-C5H4)2Zr(η2-SO4)

  摘要：

  ES-MS of dilute solutions of (bcep)ZrCl2 (1) (beep = PhP(CH2CH2-eta(5)-C5H4)(2)) in acetonitrile-water indicates the presence of three species in solution: [(bcep)Zr(H2O)(2)](2+) (2), [{(bcep)Zr(mu-OH)}(2)](2+) (3), and the singly deprotonated form of dimer 3, [{(bcep)Zr}(2)(mu-O)-(mu-OH)](+) (4). In aqueous solutions, reactivity studies investigated largely by P-31 NMR spectroscopy support the presence of 2, 3 and 4. One equivalent of fluoride was found to react immediately with 2, but slowly with 3 and 4, to give the monofluoro complex [(bcep)ZrF](+) which was isolated as the BPh4- salt. Addition of aqueous sodium sulphate gave insoluble crystals of the sulfato complex (bcep)Zr(SO4) which was characterised by X-ray crystallography. Addition of acids HX (X = Br, NO3, HSO4, HCO3) to aqueous solutions of 1 gave species observed by ES-MS corresponding to [(bcep)ZrX](+). (c) 2006 Elsevier Ltd. All rights reserved.
