The reaction of titanium tetrachloride with copper and silver: The compound CuTiCl 4

At room temperature the reaction Cu( s) + TiCl 4( l) = CuTiCl 4( s) takes place, for which the presence of oxygen is necessary. The CdCl 2 structure, but with a larger unit cell containing 6 CuTiCl 4, is proposed for this compound. Both metals are octahedrally co-ordinated to chlorine, and the oxidation states Cu(I) and Ti(III) are inferred. On heating it decomposes, CuTiCl 4( s) = Cu( s) + TiCl 4( g) and, in general, behaves as an equi-molar mixture, CuCl + TiCl 3. Silver reacts with titanium tetrachloride at room temperature, Ag( s) + TiCl 4( l) = AgCl( s) + TiCl 3( s), oxygen having no effect. This reaction is reversed by heating these products.

The Reaction of Titanium Tetrachloride with acetic acid and 1–4 dioxane

AbstractA procedure for the preparation of anhydrous titanium acetate is given. The yellow colored product has the formula Ti(C2H3O2)4 · 2 (CH3COOH. The reaction between TiCl4 and 1–4 dioxane resulted in the formation of titanium (IV) tetrachloro monodioxanate. This yellow compound was found to decompose at about 190°C. Partial hydrolysis of this compound resulted in the formation of titanium (IV) dichloro dihydroxy monodioxanate, a white compound. The latter complex was soluble in acetone, ethyl ether, water, and decomposed when heated above 300°C.

Syntheses and properties of Di(cyclopentadienyl)titanium(III)chloride

Di(cyclopentadienyl)titanium(III) chloride has been prepared in high yield by addition of tetrahydrofuran to dry mixtures of titanium trichloride and di(cyclopentadienyl)magnesium in stoicheiometric or excess amounts. Reaction of titanium tetrachloride with excess di(cyclopentadienyl)magnesium also yielded (C5H5)2TiCl in moderate yield. Some properties of the compound are given, including solid state and aqueous spectra. Magnetic measurements show the compound to have one unpaired electron per titanium atom.

Reaction of titanium tetrachloride with some ketones

Titanium tetrachloride reacts exothermally with acetone, 2-butanone, acetophenone and benzophenone to yield 1:1 solid addition complexes. The acetophenone complex containing two moles of acetophenone to one mole of titanium tetrachloride reported by Susz 1 was not obtained.

THE REACTION OF POLYISOPRENE WITH TITANIUM TETRACHLORIDE

The reaction of titanium tetrachloride with hevea, balata, and synthetic cis-polyisoprene in benzene at 80 °C has been studied. The most prominent change in the infrared spectra of these polymers is the nearly total disappearance of the 12 μ band after prolonged reaction with TiCl4. The diminution of this band, associated with the loss of the original —C(CH3)=CH— units, whether cis or trans, followed pseudo-first-order kinetics, the rate varying with [TiCl4]n, where n is 1.0 in the case of the cis polymers and 1.5 in the case of the trans polymer. Contrary to previous reports, practically no cis–trans isomerization of polyisoprene occurs in the course of this reaction, the data being explained entirely by cyclization. With the help of cis-1,4 polymers of isoprene-3-d and 2-methyl-d3-1,3-butadiene-1,1-d2, it was concluded that cyclization, involving a TiCl4-induced carbonium ion mechanism, leads to the formation of six-membered rings fused into predominantly bicyclic structures, connected by methylene groups and/or uncyclized monomer units. Each of the fused ring structures contains a single tetra-, tri-, or di-substituted double bond, the relative amounts of which are in the order tetra- > tri- > di-substituted.

Derivatives of titanium with compounds having bidentate ligands: I. Reactions of titanium tetrachloride

The reaction between titanium tetrachloride and acetyl acetone, ethyl acetoacetate, methyl acetoacetate and methyl salicylate has been studied and the compounds TiCl 2(acac) 2, TiCl 2(methyl acetoacetate) 2, TiCl 2(ethyl acetoacetate) 2 and TiCl 2(methyl salicylate) 2 have been isolated. The compound, [Zr(acac) 3]Cl, has also been prepared by the reaction between zirconium tetrachloride and acetyl acetone. By molecular weight measurements these compounds have been shown to be monomeric in nature rather than trimeric, as had been assumed by earlier workers.

Addition Compounds of Titanium

The reaction of titanium tetrachloride, chlorotitanium alkoxides, and titanium tetra-alkoxides with ammonia and pyridine has been investigated. Solid, stable, addition complexes are formed ; these react further with alcohols to give the fully substituted ester. In some of the ammonia complexes, titanium exhibits covalencies five and six.

THE PRODUCTION OF TITANIUM TRICHLORIDE BY ARC-INDUCED HYDROGEN REDUCTION OF TITANIUM TETRACHLORIDE

Finely powdered titanium trichloride of high purity was prepared by an arc-induced reaction of titanium tetrachloride with hydrogen. The hydrogen chloride by-product was passed over heated titanium, and the regenerated hydrogen and titanium tetrachloride were recirculated to the arc. The method in effect utilizes the reducing power of the titanium metal to produce titanium trichloride from titanium tetrachloride.
