Abstract

Crystal structure

Grignard reagent

Magnesium

Silicon

The only product isolated from the reaction of (Me 3Si) 3CBr with Mg in THF was, as shown by an X-ray diffraction study, (Me 3Si) 3CMg(μ-Br) 3Mg(THF) 3, which contains one four-coordinate and one six-coordinate Mg atom. A similar product, (Me 3Si) 3CMg(μ-Br) 3Mg(Et 2O) x , appears to be formed in the reaction in ether. It is suggested that the high Br/(Me 3Si) 3C ratio in the products may be associated with formation of (Me 3Si) 3C radicals (which go on to give (Me 3Si) 3CH) during the reaction with Mg.
