  Preparation of new vanadium(II) iodides and crystal structure of hexakis(acetonitrile)vanadium(II)(tetraiodide)

  摘要：

  The reaction of [VCl3(MeCN)(3)] with SiMe(3)I in acetonitrile under reflux yielded a vanadium(II) cation [V(MeCN)(6)](2+) with a counter ion I-4(2-). The latter is not symmetrical, though linear, and the reasons are discussed. The new compound diiodotetrakis (tetrahydrofuran)vanadium (II) is shown tb be a versatile precursor for vanadium diiodides, such as [VI2(Et(2)PCH(2)CH(2)PEt(2))(2)], the structure of which has also been determined.

  metallacyclopropenes, the unsaturated ligand backbone was neither degraded nor copolymerized over the course of these polymerizations. Upon hydrogenolysis of 7b, however, the metallacyclopropene backbone was partially hydrogenated, and the dinuclear (μ-H)3-bridged tantalum(V) complex 8 featuring a metallacyclopropane substructure was formed. An intermediate in this reaction was shown to catalytically hydrogenate

  LiSAr′ ( Ar ′ = C 6 H 3 - 2 , 6 - ( C 6 H 3 - 2 , 6 -Pr 2 i ) 2 ) with VI 2 (THF) 2 in THF resulted in the formation of two new V(II) and V(III) thiolate complexes. The addition of one equivalent of LiSAr′ to VI 2 (THF) 4 led to the isolation of the dimeric V(II) species V(μ-SAr′)I} 2 ( 2 ); a rare example of a structurally characterized V(II) thiolate. The thiolate ligands bridge the two vanadium centers
