Reaction of [Cu2(μ-Ph2Ppypz)2(MeCN)2](ClO4)2 (Ph2Ppypz=(2-diphenylphosphino-6-pyrazol-1-yl)pyridine) with Fe(CO)42− and X− (X=Cl, I, MeCO2 and pyrazolate)
摘要:
[Cu-2(mu-Ph(2)Ppypz)(2)(MeCN)(2)](ClO4)(2) (Ph(2)Ppypz = (2-diphenylphosphino-6-pyrazol-1-yl)pyridine) reacts with Fe(CO)(4)(2-) in tetrahydrofuran to give [Cu-2(mu-Ph(2)Ppypz)(2)(MeCN)(2)] (Fe(CO)(4)), 1, and with X- in acetonitrile or tetrahydrofuran at room temperature to afford [Cu-2(mu-Ph(2)Ppypz)(2)(mu-X)](ClO4) (X = Cl, 2; I, 3; MeCO2, 4; pyrazolate, 5). The crystal structures of 1, 3 . Et2O, 4 . Et2O and 5 have been determined by X-ray crystallography. (C) 1998 Elsevier Science S.A. All rights reserved.
