Abstract

The first example of a stable halocarbonyl of a group 4 element has been synthesized, isolated, and characterized. Treatment of (C₅Me₅)HfCl₃with sodium naphthalenide in the presence of Me2PCH₂CH₂PMe₂at -60 °C in 1,2-dimethoxyethane followed by atmospheric pressure carbonylation provides (C₅Me₅)Hf(CO)₂(dmpe)CI. The single-crystal X-ray structure of this material has been determined and is discussed in relation to spectroscopic data. Much less thermally stable zirconium and titanium analogues have also been prepared and are characterized on the basis of their spectroscopic properties.
