  摘要：

  双（三烷基氧化膦）配合物，[M（OPPr n 3）2 Br 2 ]（M = Co，Ni，Cu或Zn）和[M（OPEt 3）2 X 2 ]（M = Co，X = I; M ＝ Zn，X ＝ Br），已经合成。已进行磁化率测量（M = Co，Cu或Ni）和电子（M = Cu或Co），31 P- { 1 H} NMR（M = Zn）和红外光谱（所有配合物）已记录。表征强烈支持该络合物为假四面体的假设，在铜的情况下会发生明显的变形。暴露于SO 2时，所有配合物的显示质量均与吸收2当量的SO相称2。在此过程中，固体络合物变为液体，而油的粘度明显降低。SO 2的配位很容易在氮气流中或在减压下逆转，并且可以回收原始的配合物而不会发生明显的分解。这些性质，以及对于配位的SO 2观察到的红外吸收，表明配体结合的加合物[M {O（SO 2）PR 3 } 2 X 2 ]的形成。用热重分析法研究了配合物[Zn（OPEt

  Inorganic Grignard analogues. Reaction of cobalt powder with triorganodiiodophosphorus compounds to form [PR3I][Co(PR3)I3]. Crystal structure of [PPh3I][Co(PPh3)I3], and isolation of the novel complexes [PPh3I][Co(PPh3)IBr2] and [SbPh3I][Co(SbPh3)I3]

  摘要：

  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].
