Treatment with s-BuLi at -78o gives ɑ-lithio-ɑ-chloromethyltrimethylsilane which reacts with aldehydes and ketones to give ɑß-epoxy silanes, readily hydrolyzed to homologated aldehydes: Tetrahedron, 39, 867 (1983):

Metallation gives useful precursors of various organosilicon compounds. For use of the Grignard in the olefination of ketones, see: J. Org. Chem., 39, 3264 (1974); 52, 281 (1987).
