Abstract

Abstract ω-Lithioalkyltrimethylsilanes, prepared from ω-bromoalkyltrimethylsilanes and lithium metal, are fairly stable in diethyl ether as solvent. Upon addition of tetrahydrofuran, however, rearrangements take place, the modes of which are strongly dependent on the number of methylene groups between the lithium and the silicon atoms.
