Preparation and Structural Characterization of Bis[tris(trimethylsilyl)germyl]zinc, [(Me_3Si)_3Ge]_2Zn

摘要

Bis[tris(trimethylsilyl)germyl]zinc, [(Me_3Si)_3Ge]_2Zn, was prepared by the reaction of [tris(trimethylsilyl)germyl]lithium, (Me_3Si)_3GeLi(thf), with zinc chloride, ZnCl_2, and by the reaction of tris(trimethylsilyl)germane, (Me_3Si)_3GeH, with diethylzinc, Et_2Zn. The molecular structure of [(Me_3Si)_3Ge]_2Zn was determined by spectroscopy and X-ray diffraction methods. In [(Me_3Si)_3Ge]_2Zn, the two tris(trimethylsilyl)germyl ligands, (Me_3Si)_3Ge, are bonded in a linear fashion to the zinc atom and are staggered with respect to each other. The reactions of bis(germyl)zinc with substrates were also examined.
