TLDR
In this paper, it was shown that reaction of sodium tetrachlorotitanate(II) with trimethylamine resulted in oxidation of the halide and the formation of TiCl3,2NMe3.Abstract:
Titanium(II) chloride [or sodium tetrachlorotitanate(II)] and bromide react with methyl cyanide to yield the non-ionic complexes (TiX2,2MeCN)n which can be used as intermediates for the preparation of other complexes of the type TiX2,2L [L = pyridine, tetrahydrofuran, tetrahydropyran, ½(2,2′-bipyridyl), or ½2(1,10-phenanthroline)]. None of these products are magnetically dilute (µ ca. 1·0 B.M. at room-temperature) and they are probably halogen-bridged polymers in the solid state. Reaction of sodium tetrachlorotitanate(II) with trimethylamine resulted in oxidation of the halide and the formation of TiCl3,2NMe3. Similar oxidations occurred when pyridine reacted with titanium(II) chloride or bromide.read more
