  Abstract A new, high-yield method has been developed for the preparation of MO(CO)2I2(η2-dppm)(η1-dppm). The title compound was prepared by the reaction of [Et4N][Mo(CO)4I3] with dppm in benzene in 95% yield. It has been characterized by a single-crystal X-ray study. The crystallographic data are as follows: monoclinic, space group P21/n, a = 19.023(4) A, b = 14.439(3) A, c = 20.141(5) A, β = 100.45(2)°

  摘要为制备MO（CO）2I2（η2-dppm）（η1-dppm），开发了一种新的高产率方法。通过使[Et4N] [MO（CO）4I3]与dppm的苯反应以95％的产率制备标题化合物。它的特征在于单晶X射线研究。晶体学数据如下：单斜晶系，空间群P21 / n，a = 19.023（4）A，b = 14.439（3）A，c = 20.141（5）A，β= 100.45（2）°，V = 5440 （2）A3 Z =4。可以将围绕中心金属原子的几何形状视为是由于封端的羰基封端的八面体或碘封在矩形面上的三角形棱镜的畸变。MO（CO）2I2（dppm）2的溶液行为通过31P NMR进行了研究，结果表明该溶液是通量的。

  Bis(acetylacetonate) and bis(tropolonate) complexes of Moll were synthesized by combining [NEt4] [Mo(CO)(4)(I)(3)] and two equivalents of the ligand, followed by trapping with either an alkyne or phosphine. Alkyne complexes (trop)(2)Mo(CO)(PhC CH) (1b) and (acac)(2)Mo(CO)(Ph (R = Me (2a), H (2b)) were characterized crystallographically. The allcyne ligands undergo rapid rotation at room temperature on the NMR time scale and the barrier to rotation for the butyne complexes (LX)(2)Mo(CO)(MeC CMe) (LX = trop (1c), acac (2c)) were measured by variable temperature NMR. The rotational barrier of the tropolonate derivative lc is 1.6 kcal/mol lower than that of the acetylacetonate derivative 2c despite the fact that trop is both smaller and less basic than acac. The coordinated alkynes will readily undergo exchange with free alkyne in solution and, on a slower time scale, the CO ligand can be displaced to form the bis(alkyne) species (LX)(2)Mo(RC CR)(2) (4). The CO ligand of (LX)(2)Mo(CO)(PI1C---=,---CH) can also be readily displaced by P(OMe)(3) to form (LX)(2)Mo(P(OMe)(3))(PhC:=---CH), but larger phosphorus donors do not react. Alkyne complexes 1 and 2 will oxidize in air to the d(2) species (LX)(2)Mo(0)(RC-----CR) in which the alkyne has been rotated perpendicular to the Mo-O bond and locked in position. The synthesis of the (LX)2Mo(CO) fragment reported here provides access to oxygen ligated low-valent Mo species which have thus far remained elusive. (C) 2014 Elsevier Ltd. All rights reserved.
