When a conventional Ziegler-Natta catalyst such as titanium tetra-chloride-triethylaluminum in tetrahydrofuran is mixed with vinyl chloride, the rate of conversion is quite low (0.01497o/hr at 30°C). On the other hand, when a mixture of titanium tetrachloride and vinyl chloride is mixed with a composition consisting of vinyl chloride, triethylaluminum, and tetrahydrofuran, a substantially faster rate (1.52%/hr at 30 C) is observed in the formation of isotactic poly (vinyl chloride) [201]. 

Coordination Catalysts n Catalysts comprising a mixture of (a) an organo-metallic compound such as triethylaluminum or a transition-metal compound, such as titanium tetra-chloride. Known as Ziegler or Ziegler-Natta catalysts, they are used for the polymeri-2ation of olefins and dienes. 

High molecular weight polyindanes were obtained from p-diisopropenyl-benzene using an insoluble complex catalyst of butyllithium/titanium tetra -chloride/hydrogen chloride (Li/Ti ratio of 1.0-2.0) in toluene (72). Polymers with reduced viscosities of 0.81 possessing less than 0.05 % double bonds were obtained. Other complex catalysts, like triethylaluminum/tetrabutyltitanate/ hydrogen chloride (Al/Ti ratio of 1.0-2.0) were also useful (72). 

On treatment with trimethyl(2-propenyl)silane and titanium(IV) chloride, chiral methyl fi-formylcarboxylates give di- and tetra-substituted y-lactones with moderate to good stereoselectivity. Participation of seven-membered ring chelates was suggested65. 

Pentafluorocthyl iodide is of practical interest, particularly as a precursor of higher perfluoroal-kyl iodides. There are several patents for the preparation of the key compound from tetra-fluoroethene, iodine pentafluoride and iodine at 75-80 C in the presence of catalysts anti-mony(III) fluoride, titanium(lV) chloride, boron trifluoride, vanadium(V) fluoride, niobium(V) fluoride, and molybdenum(Vl) fluoride.11-13 The agents iodine monofluoride" and bromine monofluoride" can add to branched pcrfluoroalkcnes, e.g. perfluoro-2-methylbut-2-ene gives perfluoro-2-iodo-2-methylbutane.1415...

Titanium metal is generally manufactured by reduction of the tetra chloride with sodium or magnesium, but electrolytic methods have also been developed in an attempt to reduce costs.

These silicas are produced by a gas phase, as opposed to a solution process. There are a number of possible gas phase routes, but the predominant one is by hydration of silicon tetra-chloride. This is carried out in a flame of hydrogen and oxygen at a temperature of 1000 °C or above, and is similar to the chloride route for the manufacture of titanium dioxide pigments. Details of the process can be found in the work by Watson [39] (see also Figure 2.10). 

The reaction is normally performed at low temperatures (-30 to 0°) in methylene chloride, and is catalytic in the chiral component diethyl or diisopropyl tartrate (DET or DIPT), and in titanium tetra-isopropoxide, provided water is rigorously excluded 4 A molecular sieves may be added to ensure this. Both enantiomers of tartaric acid are commercially available, allowing the synthesis of either enantiomer of the epoxylalcohol. The key to the remarkable enzyme-like enantioselectivity lies in the complex formed from the... 

Addition of tetra(isopropoxy)titanium results in a slight increase in yield, but does not lead to an exchange of the cation which can be accomplished with tri(isopropoxy)titanium chloride (Section D.1.3.3.3.8.2.3.). In none of these cases could a trace of a second diastereomer be detected112,113. 

In order to obtain compounds with Ti-O-P and Zr-O-P units, the hexaethoxy-derivative, NsPaCOEOg, was treated with titanium and zirconium tetrachlorides. In each case, hygroscopic solids of the type NaPaCOEOiOaMCU (M = Ti or Zr) and ethyl chloride were obtained. The degree of polymerization of these solids was 1.6—1.8, and on the basis of their i.r. and n.m.r. spectra, two alternative structures, (46) and (47), were proposed. In an alternative route to the same type of compound, N3P3CI6 was treated with tetra-n-butoxytitanium in o-xylene. Butyl chloride was liberated and a solid was obtained which has been assigned the structure (48). Its thermal decomposition was studied by differential thermal analysis. 

Titanium forms three series of salts in which the element is respectively tetra-, tri-, and mono-valent. Thus, titanium and chlorine form titanium tetrachloride, TiCl4, titanium trichloride, TiCl3, and titanium monochloride, TiCl. The two last are unstable and readily pass into the higher chloride. Titanium tetrachloride shows a marked resemblance to tin tetrachloride it unites easily with hydrochloric acid in solution, with formation of the complex acid, ehloro-titanic acid, [TiCl6]tI2, and forms many crystalline products with other chlorides. It also unites with ammonia, forming ammines.
