Synthesis and molecular structure of [Mg(CH2SiMe3)(μ3-OCH2SiMe3)]4

Crystalline [Mg(CH2SiMe3)(μ3-OCH2SiMe3)]4 has been identified as the product of oxidation of ClMgCH2SiMe3 with traces of O2. Its formation requires the formation of Mg(CH2SiMe3)2 via the Schlenk equilibrium. The compound is a rare example of a structurally characterized magnesium alkyl alkoxide with Mg4O4 cubane structure.

The reaction of traces of oxygen with ClMgCH2SiMe3 gave crystalline [Mg(CH2SiMe3)(μ3-OCH2SiMe3)]4 containing a Mg4O4 cubane core.Figure optionsDownload as PowerPoint slide
