  Exchange of isonitrile ligands in the complex [Mo(O)Cl(CNMe)4]+ by the tetraphos ligand prP4: Stereochemical influences on the reaction course

  摘要：

  Reaction of [Mo(O)Cl(CNMe)(4)](+) with the linear tetraphos ligand meso and rac prP(4) leads to a mixture of [Mo(O)Cl(kappa(4)-meso-prP(4))](+) and [Mo(O) Cl(CNMe)(kappa(3)-rac-prP(4))](+) which are identified by X-ray structural analysis and/or P-31 NMR spectroscopy. In the meso kappa(4)-product both of the phenyl groups of the central phosphorus atoms are oriented towards the oxo ligand whereas in the rac kappa(3)-product one of these phenyl groups is oriented to the oxo and the other to the chloro ligand. The origin of the different coordination modes lies in the different steric demands of the oxo and chloro ligands. The influences of the steric interactions are enhanced by the fact that exchange of the fourth isonitrile is difficult. This hypothesis is supported by the preparation of the complex [Mo(O)Cl(CNMe)(dpepp)]PF6 whose isonitrile ligand is inert towards exchange by monophosphines, even under drastic conditions.

  具有四磷烷配体的第一个 Chatt 型双（二氮）-钼（0）配合物的立体选择性合成

  摘要：

  第一个具有四磷烷配体的 Chatt 型 MoO 二氮配合物已被制备，并通过 NMR 以及红外和拉曼光谱进行表征。重要的是，所采用的反应路线允许该复合物的立体定向合成为反式-[Mo(N2)2(meso-prP4)]（prP4 = 具有中心丙烯桥的四磷配体）。反应过程中的立体选择性是由氧化碘化钼 (IV) 前体 [Mo(O)I(prP4)]+ 诱导的，该前体将 prP4 的桥连 P 原子的两个苯基团引导成内消旋构型。该论文建立了一种合成单核 MoO 二氮和相关钼配合物与多齿磷烷配体的一般策略，这是迄今为止不可能的。而且，由于两个二膦单元通过烷基桥连接，所得四磷 N2 配合物在合成固氮的 Chatt 循环反应中比传统的双（二磷）配合物表现出更高的热力学稳定性。(© Wiley-VCH Verlag GmbH & Co.

  The stereochemistry of prP(4) (1,1,4,8, 11, 1 1-hexaphenyl- 1,4,8, 1 1-tetraphosphaundecane) and its coordination properties in mononuclear complexes are explored. The free ligand is obtained as a mixture of meso and rac diastereomers from the reaction of dilithium 1,3-bis(phenylphosphido)propane-tetrakis(tetrahydrofuran) ("Lippp") with 2 equiv of 1-chloro-2(diphenylphosphino)ethane. Reaction of prP(4) with FeCl2 and KSCN leads to cis- and trans[Fe(NCS)(2)(prP(4))] complexes of the meso and the rac ligands; the composition of this mixture has been fully analyzed. The iron isothiocyanato complexes cis-alpha- and trans-[Fe(NCS)(2)(racprP(4))] have been characterized by X-ray structure determinations. The UP NMR spectrum of the free tetraphos ligand shows an AA'XX' coupling scheme with three groups of signals centered at -20.6 and -20.7 ppm and at -12.4 ppm, which belong to the rac and meso isomers, respectively. P-31 NMR spectra of the cis and trans iron isothiocyanato complexes of rac-prP(4) exhibit AA'XX' patterns as well, which can be reproduced by simulation. trans[Fe(NCS)(2)(meso-prP(4))] is identified by its P-31 NMR spectrum, which is similar to that of its rac counterpart. On the basis of NMR spectroscopy it is found that the cis-alpha complex of the rac ligand converts into the trans-rac complex with a half-life of approximately 2 days. Infrared and Raman spectra of the cis-alpha and trans isomers of [Fe(NCS)2(rac-prP4)] reveal characteristic differences in the region of the C-N stretching vibrations.
