The reaction of TiCl4 with 2-trimethylsiloxyphenyl isocyanide 1 is described.At -10 deg C reaction of TiCl4 with 1 in n-hexane yields the air-sensitive octahedral diisocyanide complex cis-2> 2.This complex crystallizes from n-hexane as solvate 2*C6H14 and was characterized by X-ray crystallography.At room temperature TiCl4 reacts with 1 in toluene to give an orange air-sensitive compound 3, which was not completely characterized.Elemental analyses indicate the formation of a complex composed of one molecule of TiCl4 and one molecule of 1.IR spectroscopy shows that no isocyanide ligand is present in 3.Keywords: Isocyanide complex; Titanium; X-ray crystallography
