A comparative study of 1,5-cyclooctadiene complexes of W(0) and W(II).X-ray crystal structure of [W(CO)_4(eta~2,eta~2-1,5-C_8H_(12))] and [W(mu-Cl)(SnCl_3)(CO)_3(eta~2,eta~2-1,5-C_8H_(12))]

摘要

The photoinitiated oxidative addition of 1 equiv.of SnCl_4 to [W(CO)_4(eta~2,eta~2-1,5-C_8H_(12))] (1) affords the first cyclooctadiene complex of tungsten(II) [W(mu-Cl)(SnCl_3)(CO)_3(eta~2,eta~2-1,5-C_8H_(12))] (2).The structure of compounds 1 and 2 in solution has been established by IR,~1H and ~(13)C NMR spectroscopic methods and found to be in accordance with the crystal structure determined by X-ray diffraction studies.
