Aluminum triiodide

Zirconium tetraiodide [13986-26-0], Zrl, is prepared directly from the elements, by the reaction of iodine on zirconium carbide, or by halogen exchange with aluminum triiodide. The reaction of iodine with zirconium oxide and carbon does not proceed. The physical properties are given in Table 7. 

Iodosilane has been prepared by the cleavage of phenylsilane10 or chloro-phenylsilane11,12 with hydrogen iodide, and by the reaction of monosilane with hydrogen iodide in the presence of a catalytic amount of aluminum triiodide.4 The latter method has been extended to prepare the methylated iodosilanes.5,13 Iodotrimethylsilane has also been prepared by the cleavage of trimethylphenyl-silane with iodine.14... 

The aluminum/aluminum triiodide catalyzed addition of iodine monofluoride to perhaloal-kenes with terminal CF2 groups provides high yields of the products in the case of tetra-lluoroethene, chlorotrifluoroethene, hexafluoropropene, and 1,1-dichloro-2,2-difluoroethcne, but rather moderate or low yields for 1,2-dichloro-l,2-difluoroethene, 1-chloro-2,2-di-fluoroethene, and trifluoroethene.9... 

Protactinium pentaiodide was first prepared by reacting the pentox-ide with aluminum triiodide at 400°C in a vacuum (104). For large scale preparations, however, direct union of the elements or metathesis of the pentaohloride or pentabromide with an excess of silicon tetraiodide are best (40). The latter reactions take place rapidly at about 180°C in vacuo and the black crystalline product is then purified by vacuum sublimation at 400°-450°C. Silicon tetraiodide also reacts with protactinium pent-oxide, but temperatures in excess of 600°C are required with the reaction vessel completely enclosed in the furnace, and the yield is only about 70% (40). 

Trifluoromethyl groups are lost from tris(trifluoromethyl)arsine on heating with aluminum trichloride, aluminum triiodide, or boron triiodide 130).
