• 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). For Ni-catalyzed reaction of the Grignard with allylic dithioacetals, see: J. Org. Chem., 53, 5582 (1988); Org. Synth. Coll., 9, 727 (1998); for an example with reaction scheme, see trans-Cinnamaldehyde, A14689.
• Treatment with s-BuLi at -78o gives ɑ-lithio-ɑ-chloromethyltrimethylsilane which reacts with aldehydes and ketones to give ɑ?-epoxy silanes, readily hydrolyzed to homologated aldehydes: Tetrahedron, 39, 867 (1983):
• For a review of the chemistry of chloromethyltrimethylsilane, see: Synthesis, 717 (1985).
