• Other conditions for addition to aldehydes include: phase-transfer catalysis: Angew. Chem. Int. Ed., 12, 845 (1973), KOH in acetonitrile: Tetrahedron Lett., 23, 5283 (1982), or KF on alumina: Tetrahedron, 41, 1259 (1985). With aryl aldehydes, the use of KO-t-Bu gives improved results by suppressing the competing Cannizzaro reaction: Org. Prep. Proced. Int., 27, 219 (1995). A simplified, solvent-free method employing KO-t-Bu has been reported for ketones: Heterocycles, 46, 185 (1997). With excess of the sulfonium ylide, ketones or epoxides give good yields of allylic alcohols, whereas aldehydes give poor yields. Under similar conditions, the sulfoxonium ylide gives oxetanes: Tetrahedron Lett., 35, 2009, 5449 (1994).

• The ylide, generated with strong base, is a powerful methylene transfer reagent, converting aldehydes and ketones to epoxides; reaction with ɑß-enones also gives epoxides (contrast Trimethyl­sulfoxonium iodide, A14589): J. Am. Chem. Soc., 87, 1353 (1965):

• Addition to vinyl sulfones gives cyclopropyl sulfones: J. Org. Chem., 29, 3277 (1964). Similarly, vinylsulfonates and sulfonamides give cyclopropanes in fair to good yields: J. Org. Chem., 33, 3849 (1968).
