Synthesis and characterization of titanium tetraisocyanide complexes, [CpTi(CNXyl)4E], E=I, SnPh3, and SnMe3
摘要:
Oxidation of [CpTi(CO)(4)](-) by I(2), Ph(3)SnCl, and Me(3)SnCl in the presence of four equivalents of CNXyl, Xyl = 2,6-dimethylphenyl, affords unprecedented titanium tetraisocyanide complexes, [CpTi(CNXyl)(4)E], E = I, SnPh(3), SnMe(3). 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)(2)I(2)], which was also characterized by X-ray crystallography. (C) 2007 Elsevier B.V. All rights reserved.
