Preparation of (η5-Alkoxyfluorenyl)(η6-p-Cymene)-Sandwich Ruthenium(II) Complexes
摘要:
Diazoalkane complexes [RuCl(N(2)CArlAr2)(n(6)-p-cymene)P]BPh4 [Arl = Ph; Ar2 = Ph or p-tolyl; P=PPh(OEt)(2) or P(OEt)(3)] were prepared by allowing p-cymene complexes RuCl2 (n(6)-p-cymene)P to react with diaryldiazoalkane ArlAr2CN(2). Treatment of the triisopropylphosphine complex RuCl2(n(6)-p-cymene)(P'Pr-3) with 9-diazofluorene yielded the (n(5)-alkoxyfluorenyl)(n(6)-p-cymene)-sandwich derivative [Ru(n(5)-RO-fluorenyl)(n(6)-p-cymene)]BPh4 (R = Mc. Et) The complexes were characterized spectroscopically (IR and H-1, C-13. P-31 NMR) and by X-ray crystal structure determination of the [Ru(n(5)-EtO-fluorenyl)(n(6)-cymene]BPh4 derivative.
