  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].

  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

  R的新颖反应3与八羰基二钴PI化合物进行了研究，并与涉及R的反应以前的研究3 PI 2种化合物与钴金属粉末。由两个反应产生的产物具有相同的化学计量，但是令人惊讶地具有不同的结构。红外和拉曼光谱研究以及X射线粉末衍射清楚地表明，由R 3 PI 2与Co 2（CO）8反应得到的产物是[R 3 PI] [CoI 3（PR 3）]的新异构形式。]，与从R 3反应中分离出的产物相比PI 2与钴金属粉末。报告了[R 3 PI] [CoI 3（PR 3）]的这种新异构形式的七个实例，并已通过元素分析，拉曼光谱和定量电子光谱以及磁数据进行了表征，后者表明发生了一些反铁磁耦合。报告和讨论了对这些反应的反应机理的一些一般研究。
