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 ( i Pr 3 Si) 2 SiH 2 with [( t Bu) 2 Hg] followed by lithiation in THF. Irradiation of 1 produces [Li( i Pr 3 Si) 2 Si] . ( 2 ), the first silyl radical with an α ‐Si‐Li bond detected by EPR spectroscopy (see spectrum).
