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).
