Oxidation of [CpTi(CO)4]- by I2, Ph3SnCl, and Me3SnCl in the presence of four equivalents of CNXyl, Xyl = 2,6-dimethylphenyl, affords unprecedented titanium tetraisocyanide complexes, [CpTi(CNXyl)4E], E = I, SnPh3, SnMe3. These have been isolated and characterized by spectroscopic methods as well as single-crystal X-ray crystallography. A by-product of the iodine reaction was the Ti(III) complex, [CpTi(CNXyl)2I2], which was also characterized by X-ray crystallography.
