  摘要：

  The reaction of [Fe2(CO)9] with compounds of stoichiometry R3EX2 [R3E = Ph3P, (p-MeOC6H4)3P, Me2PhP, Me3As or Ph3Sb, X = I; R3E = Ph3P, Ph3As or Me3As, X = Br] has been investigated and shown to yield diverse products. A series of complexes with the ionic structure [R3EX][Fe(R3E)X3] [E = P, R3 = Ph3, Me2Ph or (p-MeOC6H4)3, X = I; R3E = Me3As; X = I or Br] has been obtained. The reaction of [Fe2(CO)9] with Ph3PBr2 and Ph3AsBr2, however, resulted in the formation of the iron(III) complexes [(Ph3E)2Br][FeBr4]. Hydrolysis of [(Ph3P)2Br][FeBr4] by trace quantities of water produces [(Ph3PO)2H][FeBr4], the crystal structure of which has been determined. Triphenylantimony diiodide reacted with [Fe2(CO)9] yielding the surprising ionic adduct [Ph4Sb][FeI4].Ph3SbI2, remarkable not only for the phenyl migration at the antimony atom, but also for the formation of the rare [FeI4]- anion from a zerovalent iron carbonyl complex. The reaction of [Fe2(CO)9] with the milder diphosphine tetraiodide, I2Ph2PCH2CH2PPh2I2, produced [Fe(CO)3(Ph2PCH2CH2PPh2)I][I3], a complex in which three CO ligands are retained.

  The novel reaction of R3PI compounds with dicobalt octacarbonyl has been investigated and compared to previous studies involving the reaction of R3PI2 compounds with cobalt metal powders. The products produced from both reactions have identical stoichiometries but, surprisingly, possess different structures. Infrared and Raman spectroscopic studies and X-ray powder diffraction clearly show that the

  The reactions of a large number of triorganodiiododophosphorus compounds, R3PI2 [R3 = Et3, Pr(n)3, Bu(n)3, PhMe2, Ph2Me, Ph2Pr(n), Ph3 (o-,m- or p-MeC6H4)Ph2, or (m-MeC6H4)3], with unactivated cobalt metal in dry diethyl ether have been studied. All reactions produce the novel ionic complexes [PR3I][Co(PR3)I3] in quantitative yield, illustrated crystallographically for [PPh3I][Co(PPh3)I3]. However, where R3 = PhMe2 both the ionic complex and the cobalt(III) complex [Co(PPhMe2)2I3] are produced from the same reaction. The previously reported isolation of the 'frozen transition-state complex' [Co(PBun3)3I8] from the reaction of Bun3PI2 with cobalt powder has been reinvestigated; when allowed to proceed to completion, the reaction produces the ionic complex described above. The compound Ph3PIBr reacts with cobalt powder to produce the mixed-halide ionic complex [PR3I][Co(PR3)IBr2]. All the complexes [PR3I][Co(PR3)I3] have been studied using Raman and visible spectroscopy, the latter confirming the tetrahedral geometry of the cobalt anion. Very little reaction is observed with the corresponding dibromophosphorus compounds, R3PBr2, but in some cases visible spectroscopic studies on the trace of complex formed suggest a tetrahedral cobalt(II) species, perhaps similar to the iodo-complexes described above. Additionally, Ph3SbI2 reacts with cobalt metal in an analogous way to Ph3PI2 to produce the novel complex [SbPh3I][Co(SbPh3)I3].

  Reactions of dihalogenotriorganophosphorus compounds R3PX2 (X = Br or I) with unactivated coarse-grain nickel metal powder have been investigated. The nature of the nickel phosphine complexes formed is remarkably dependent on both R and X. Where R not-equal Me and X = I the nickel(II) complexes [R3PI] [Ni(PR3)I3] are formed, analogous to, but not isostructural with, similar cobalt complexes of the same stoichiometry formed from cobalt powder and R3PI2. Quantitative electronic spectroscopic studies indicated that, surprisingly, the [R3PI][Ni(PR3)I3] complexes all have predominantiy square-planar geometry around nickel. Where R = Me and X = 1, the nickel(III) complex [Ni(PMe3)2I3] is obtained in quantitative yield, the other product being diiodine. Reaction of nickel powder with Me2PhPI2 yields both the nickel(II) complex, [MePhPI][Ni(PPhMe2)I3], and the nickel(III) complex, [Ni(PPhMe2)2I3]. These observations again mirror analogous cobalt reactions. Reaction of the analogous dibromo compounds, R3PBr2, with nickel powder is extremely sensitive to the nature of R. Where R = Me, Et or Pn(n) no reaction occurs; where R3 = PhMe2 the square-planar complex [Ni(PPhMe2)2Br2] and an octahedral complex of stoichiometry Ni(PPhMe2)2Br, are obtained in equal yield. Where R3 = Ph2Pr(n) the octahedral complex [Ni(PPh2Prn)2Br4] is formed with a trace of the planar complex [Ni(PPh2Prn)2Br2], and where R = Ph the octahedral complex [Ni(PPh3)2Br4] is formed in quantitative yield. The complex [Ni(PPhMe2)2Br] has been crystallographically characterised: monoclinic, space group P2(1)/a, a = 10.018(2), b = 10.249(1), c = 10.138(1) angstrom and Z = 2 (molecule centrosymmetric).

  The novel reaction of crude manganese metal powder with dibromo- and diiodo-phosphoranes, R3PX2, has been studied. Reaction of the phosphoranes R3PI2 (R = phenyl or substituted aryl) with manganese allows insertion of the metal into P-X bonds and gives the monomeric tetrahedral complexes [MnI2(PR3)2] and MnI2. However, reaction of R3PX2 (R3 = mixed aryl/alkyl, trialkyl; X = Br or I) with manganese, whilst once again proceeding via insertion into P-X bonds, now leads to the quantitative isolation of the polymeric complexes [MnX2(PR3)}n], thus illustrating the subtle nature of these reactions. Examples of both types of complex have been crystallographically characterised and represent rare examples of such. There is some evidence that where R3 = Ph2Me an equilibrium exists and both types of complex, [MnI2(PPh2Me)2] and [MnI2(PPh2Me)}n] can be detected from the same reaction.
