Abstract

Radical developments in silyllithium chemistry: The preparation and X-ray structure of 1, the first compound with geminal Hg-Si-Li bonding, is reported. Compound 1 is obtained by the reaction of (iPr₃Si)₂SiH₂ followed by lithiation in THF. Irradiation of 1 produces [Li(iPr₃Si)₂Si]^· (2), the first silyl radical with an α-Si-Li bond detected by EPR spectroscopy (see spectrum).
