TiCl3

Tiianium ll) chloride, TiCl2- Black powder (TiCl4 plus Ti or heat on TiCl3). Strong reducing agent, immediately reduces water. Forms some complexes. 

Ziegler-Natta Polymerization. The polymeri2ation of propylene with Ziegler-Natta catalysts, ie, complexes of TiCl3—(C2H3)3A1 on MgCl2... 

Oyychlorides. Hydrolysis of TiCl yields a number of products, the composition of which depends on the hydrolysis conditions. In the TiCl —HCl—H2O system, species ranging from Ti(H20) g through TiCl(H20) 3 to TiCl3(H20) , as the acid concentration increases, has been reported (141).

TiCl3, H2O, It, 1 h, 85% yield.This is an excellent reagent that works when cleavage of a methoxy oxime with chromous ion fails. 

The benzyloxy group on a /3-lactam nitrogen was cleaved by hydrogenolysis (H2, Pd-C) or by TiCl3 [MeOH, H2O, (NH4)2C03, Na2C03]. ... 

Factors affecting laboratory polymerisation of the monomer have been discussed" and these indicate that a Ziegler-Natta catalyst system of violet TiCl3 and diethyl aluminium chloride should be used to react the monomer in a hydrocarbon diluent at atmospheric pressure and at 30-60°C. One of the aims is to get a relatively coarse slurry from which may be washed foreign material such as catalyst residues, using for example methyl alcohol. For commercial materials these washed polymers are then dried and compounded with an antioxidant and if required other additives such as pigments. 

Propargyl ethers are cleaved with TiCl3-Mg in THF, 54-92% yield. Allyl and benzyl ethers were not cleaved phenolic propargyl ethers are also cleaved. ... 

Hydrate isomerism of TiCl3.6H20, yielding [TiCl2(H20)4]" CU as one of the isomers, has already been referred to (p. 965) and analogous complexes are formed by a variety of alcohols. Neutral complexes, [T1L3X3] have been characterized for a variety of ligands such... 

The a-form has the a-TiCl3 structure with 6-coordinate ruthenium and a rather long Ru-Ru distance (3.46A) compared with the /3-form where... 

The formation of surface defects of a crystal lattice. It was observed while using crystal compounds of transition metals as catalysts [e.g. as was shown by Arlman (171, 173), for a TiCl3 surface defects appear on the lateral faces of the crystal]. In this case low surface concentration of the propagation centers should be expected, as is illustrated in the case of polymerization by titanium dichloride (158). The observed...
