  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].

  AbstractElementares Chlor, Brom und Jod reagieren unter geeigneten Bedingungen mit aliphatischen, hydroaromatischen und aromatischen tertiären Phosphinen im Mol‐Verh. 1:1. Die Additionsverbindungen sind mit Ausnahme des (C6H11)3PJ2 und (C6H5)3PJ2 äußerst feuchtigkeitsempfindlich. Auf Grund ihres salzartigen Verhaltens können sie als Phosphoniumsalze aufgefaßt werden.Die Phosphindihalogenide setzen sich mit SbCl5, SbBr3 und HgJ2 im Sinne einer Halogen‐Donator‐Akzeptor‐Reaktion um. Die dabei entstehenden Phosphoniumsalze zeigen die Leitfähigkeiten binärer Elektrolyte. Sie enthalten das Phosphoniumkation [R3PX]+. Während Phosphindichloride und Phosphindibromide in Lösung mehr als Neutralmolekeln vorliegen, wird für Phosphindijodide in Lösung eine Dissoziation in [R3PJ]+ und J−‐Ionen bewiesen.Aus Phosphindihalogeniden und Reinecke‐Salz können in wäßrigem Alkohol Phosphinoxyd‐Reinecke‐Säure‐Additionsverbindungen im Verhältnis 1:1, 2:1 und 4:1 dargestellt werden. Bei der Solvolyse von Tricyclohexylphosphindibromid in CH3OH bei Anwesenheit von Reinecke‐Salz entstehen [(C6H11)3POCH3] [Cr(SCN)4(NH3)2] und (C6H11)3P(OCH3)2 · H[Cr(SCN)4(NH3)2].Beim Umkristallisieren des Tricyclohexylphosphindijodides aus C2H5OH in Gegenwart von Sauerstoff entsteht [(C6H11)3PO]2 · HJ3.
• Inorganic grignard analogues. Reaction of nickel powder with dihalogenotriorganophosphorus compounds to form nickel-(II) and -(III) phosphine complexes; isolation of planar [Ni(PPh3)I3]? and the crystal structure of [Ni(PPhMe2)2Br2]

  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).
