So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Herberhold, Max; Kniesel, Heidemarie; Haumaier, Ludwig; Thewalt, Ulf researched the compound: Bromoferrocene( cas:1273-73-0 ).Recommanded Product: 1273-73-0.They published the article 《Triferrocenyl complexes of tungsten(VI): the molecular structure in the solid state and dynamic behavior in solution of triferrocenyl(ferrocenyloxy)oxotungsten, WO(OFc)Fc3》 about this compound( cas:1273-73-0 ) in Journal of Organometallic Chemistry. Keywords: ferrocenyltungsten preparation crystal structure; tungsten triferrocenyl preparation mol structure. We’ll tell you more about this compound (cas:1273-73-0).
WO(X)Fc3 [X = Cl (I), OMe (II), OFc (III), OBu (IV); Fc = ferrocenyl] were obtained by treating WOCl4 with ferrocenyllithium in THF. Reaction of WOCl4 with a threefold excess of FcLi gives I, which may be converted into II using KOMe. Reaction of WOCl4 with a sixfold excess of FcLi gives a mixture containing III and IV in addition to ferrocene and biferrocene. According to the x-ray crystallog. anal., III has a trigonal-bipyramidal structure with three ferrocenyl ligands occupying the equatorial positions and an axial ferrocenoxy group coordinated trans to the oxo ligand. The three W-C(ferrocenyl) (average 2.092 Å) and the O-C(ferrocenyl) [1.33(1) Å] bond distances are remarkably short. The axial tungsten-oxygen distances correspond to a W:O double and a W-O single bond, resp. The 1H and 13C NMR spectra of III are temperature dependent because of a hindered rotation of the ferrocenyl ligands around the W-C(ferrocenyl) bonds.
