Experimental and theoretical charge density studies and molecular orbital analyses suggest that the complexes [Cp2Ti(PMe3)SiH 2Ph2] (1) and [Cp2Ti(PMe3)SiHCl 3] (2) display virtually the same electronic structures. No evidence for a significant interligand hypervalent interaction could be identified for 2. A bonding concept for transition-metal hydrosilane complexes aims to identify the true key parameters for a selective activation of the individual M-Si and Si-H bonds. Copyright

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1271-19-8 is helpful to your research. Computed Properties of C10Cl2Ti

Group 4 alkylmetal(IV) halides of the type Bu2MtCl2, generated in hydrocarbon media at -78C by treating MtCl4 with 2 equiv of n-butyllithium, function as strong bases toward a variety of Bronsted acids, E-H, where E = cyclopentadienyl or substituted cyclopentadienyl, 1-alkynyl, indenyl, alkoxy, aryloxy, and disubstituted amino, to form metallocene and nonmetallocene procatalysts, E2MCl2, expeditiously and generally in high yield.

Long-lived ligand-to-metal charge transfer (LMCT) excited states based on a zirconium complex (ca. 2000 mus) and a hafnium complex (ca. 300 mus) are first characterised with use of the Cp2Zr(IV)Cl2 and Cp2Hf(IV)Cl2. The tendency in the observed photophysics (absorption and phosphorescence spectra, lifetimes, and quantum yields) in the homologous group IVB metallocenes Cp2M(IV)Cl2 is discussed in view of the nature of the unique metal (Ti, Zr or Hf)-ligand pi-bonding character.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. SDS of cas: 1271-19-8, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1271-19-8, in my other articles.

The reaction of Cp2TiCl2 with o-mercaptophenolate in the presence of a base (Et3N or NaOMe) afforded the complex (BnMe3N)2[Ti(o-SC6H4O)3] or (Et4N)2[Ti2(o-SC6H4O)4(OMe)2]·2H2O under slightly varied conditions. Single-crystal X-ray diffraction studies showed that the Ti(IV) geometry in both complexes is a severely distorted octahedron with average trans-angles of 162.2and 159.1(2), respectively. Crystallographic data for (BnMe3N)2[Ti(o-SC6H4O)3]: a = 9.884(3), b = 16.501(7), c = 23.028(7) A; beta = 99.89(3), V = 3700.2(22) A3, Z = 4, final R = 0.050 for 3134 observed reflections; for (Et4N)2[Ti2(o-SC6H4O)4(OMe)2]·2H2O: a = 8.953(4), b = 10.148(3), c = 14.527(3) A; a = 73.16(2), beta = 73.00(3), gamma = 83.56(4), V = 1207.4(9) A3, Z = 1, final R = 0.082 for 2233 observed reflections. The isolations of (BnMe3N)2[Ti(o-SC6H4O)3] provides strong evidence for the synthon character of [Ti(mp)3]2-, which was previously predicted to be present in the complex (Et4N)2[Ti(mp)3Na(MeOH)2]2. Both electronic and 1H NMR spectra showed a similar rigidity of the mp chelate rings to Ti(IV) in the complexes.

Lithiation of p-tBu-calix[4]arene followed by reaction with titanocene dichloride affords a novel tetranuclear titanium(IV) monocyclopentadienyl complex, wherein a single calix[4]arene in a cone conformation provides O-phenoxy coordination to four titanium atoms, with additional mu-oxo bridging between titanium centres in an eight membered ring.

Aziridines activated by N-acylation are opened to the higher substituted radical through electron transfer from titanocene(III) complexes in a novel catalytic reaction. This reaction is applicable in conjugate additions, reductions, and cyclizations and suited for the construction of quaternary carbon centers. The concerted mechanism of the ring opening is indicated by DFT calculations.

Thermal alpha-H abstraction from (C5H4R)2Ti(CH2CMe3)2 (R = H, Me) produces reactive titanocene neopentylidene intermediates under mild conditions, that can either be trapped with PMe3 to yield the alkylidene complexes (C5H4R)2Ti(CHCMe3)PMe3, or add C-H bonds of hydrocarbon substrates R’H (R’H = benzene, p-xylene) to the Ti=C double bond to produce (C5H4R)2Ti(CH2CMe3)R’; an alternative reaction pathway, insertion of the alkylidene moiety into the cyclopentadienyl C-C bond, has been observed in the presence of THF.

Reduction of red Cp2TiCl2 (Cp = cyclopentadienyl) with zinc dust in acetonitrile produces a blue solution of [Cp2Ti(NCMe)2]+, which when exposed to air rapidly discolors to bright yellow. This behavior makes the blue solution a handy visual indicator for the presence of oxygen, but the chemistry is considerably more complicated than the primary colors suggest at first glance. Real-time mass spectrometric and colorimetric analysis reveals that oxidation from Ti(III) to Ti(IV) produces a host of oxygen-containing complexes, whose appearance parallels the observed color changes.

The Cp2*TiAlH4 complexes (Cp* = Cp, MeCp, Me3CP, Me4CP, Me5CP and EtMe4Cp) were prepared from Cp2*TiCl and LiAlH4 in toluene.On aging, all the Cp2*TiAlH4 complexes, except for the peralkylated ones, formed paramagnetic clusters composed probably of the Cp2*TiH and Cp2*TiAlH4 units.The clusters reacted with an excess of butadiene to give (1-methyl-eta3-allyl)titanocenes and Cp2*TiAlH4 complexes.The Cp2*TiAlH4 complexes yielded the same allyltitanocene products, but in a slower subsequent reaction.Aging of the peralkylated Cp2*TiAlH4 complexes led to the thus far unknown paramagnetic products which are unreactive to butadiene.The (1-methyl-eta3-allyl)titanocenes were also prepared from Cp2*TiCl by reaction with LiAlH4 in the toluene/butadiene mixture.The Cp2*TiAlH4 complexes which formed transiently in these systems were found to have ESR parameters different from those obtained in pure toluene.The effects were established of the methyl substituents in the Cp* ligands on the ESR and electronic absorption spectra of the Cp2*TiAlH4 complexes and (1-methyl-eta3-allyl)titanocenes.

Bimetallic titanium and zirconium complexes with bridges (X) between Cp ligands were compared to Cp2MCl2 as catalysts in the presence of nBuLi for the dehydrocoupling of PhSiH3 to polyphenylsilane. The monobridged bimetallic complexes developed were of the composition [ mu-X(C5H4)2ICpMCl2]2 with X = Me2Si (M = Ti, Zr), Me2SiCH2SiMe2 (M = Ti) and Me2SiCH2CH2SiMe2 (M – Ti, Zr). The dibridged bimetallic complexes examined were of the type [mu,mu-(Me2Si)2(C5H3)2ICp?TiCl2l2 (Cp? = Cp, trans isomer, Cp? = Cp *, trans and cis isomers). There was not a significant difference in the molecular weight of the polysilane produced from Cp2TiCl2 and the bimetallic titanium complexes after 48 h of reaction. However, the polysilane which was generated from the bimetallic complex [ mu-(Me2Si)(C5H4)2ICpZrCl2]2 was approximately twice the molecular weight compared to that obtained from Cp2ZrCl2. The structure of the bimetallic complex [ mu-(Me2SiCH2CH2SiMe2)(C5H4)2ICpZiCl2]2 was determined by X-ray diffraction (monoclinic, P21/n, a = 8.7297(3)A, b = 6.7890(2)A, c = 24.9343(7)A, beta = 93.7850(10), Z=2).
