  ∑-Alkenyl and halogeno complexes of vanadium (I and II). The crystal structures of (C1V(CO)2(Ph2PCH2CH2PEt2)2 · benzene, Br2V(Me2PCH2CH2PMe2)2 and I2V(Me2PCH2CH2PMe2)2 · toluene

  摘要：

  Various sigma-alkenyl complexes of the general composition (alkenyl)V(CO6-npm (where n = 2, 3 and p(m) is a potentially m-dentate phosphine coordinated through n of its donor centres, n less-than-or-equal-to m) have been prepared by photo-induced hydrovanadation of the alkynes 2-butyne, 1-hexyne, 3-hexyne and 3,3-dimethyl-1-butyne. In each case the Z isomer is formed exclusively or as the predominant product. Reaction of hexacarbonylvanadate with pyridinium bromide and p(m) leads to the bromo complexes BrV(CO)6-npm (n = 2-4). In the case of p(m) = Me2PCH2CH2PMe2 (dmpe), the complex Br2V(dmpe) is also formed. The complex I2V(dmpe)2 . toluene was obtained as a by-product from the reaction between [Et4N][V(CO)4dmpe] and perfluoro-isopropyl iodide. The face-capped, trigonal-prismatic complex ClV(CO)2(pepe)2 . benzene (pepe = Ph2PCH2CH2PEt2) was obtained from the photo-reaction between HV(CO)4pepe and [Et4N]Cl. Single-crystal X-ray diffraction studies were carried out on all three complexes. The V-50 NMR chemical shifts for the seven-coordinate complexes XV(CO)npm have been used to arrange the ligands X in a magnetochemical series of ligand strengths (alkenyl congruent-to alkyl < SiMe3 < H congruent-to Br congruent-to I < O2CR < Cl congruent-to N3 < CN).
