Dialkylation with alkyl halides affords, after hydrolysis, symmetrical ketones: Synthesis, 117 (1974). This reaction has also been applied to the synthesis of cyclobutanones and other cycloalkanones: Tetrahedron Lett., 3653 (1974); 2767 (1975). A Knoevenagel reaction with aryl aldehydes gives the ketene thioacetal monosulfoxide, readily solvolyzed in alcoholic HCl to an arylacetic ester: Tetrahedron Lett., 1383 (1972):
- With ketones, the lithio-derivative gives, after hydrolysis, ɑ-hydroxy aldehydes, not readily available by other routes: Tetrahedron Lett., 2681 (1972). Elimination from the intermediate adduct has also been used as a route to substituted acetic acids: Synthesis, 880 (1979).
- Readily undergoes metallation with NaH, n-BuLi, etc. to give a useful formaldehyde anion synthon. Products are readily hydrolyzed by acid.
