Acetone is a polar, aprotic solvent used in the synthesis and isolation of both organic and inorganic compounds and complexes. It plays a vital role in Jones oxidation. It is utilized for rinsing laboratory glasswares due to its low cost and volatility. It is used in the manufacture of various chemicals such as methyl isobutyl ketone, mesityl oxide, diacetone alcohol, acetic acid, iodoform, bromoform, rayon, photographic films, paint and varnish removers. It is also useful in the synthesis of t-butanesulfinamide, terpenes, thiol-stabilized gold colloids, calixphyrin macrocycles and trispyrazolylborate platinum compounds. It plays an important role in protein crystallization.
Precursor of dimethyldioxirane, by reaction with K monopersulfate, and isolation in solution by low temperature distillation. For details, see: Chem. Ber., 124, 2377 (1991). It is an excellent reagent for rapid, stereospecific epoxidation of alkenes under mild conditions: J. Org. Chem., 50, 2847 (1985); Org. Synth. Coll., 9, 288 (1998). For improved work-up procedure allowing the possibility of more concentrated solutions or the isolation of acetone-free material, see: Tetrahedron Lett., 37, 3585 (1996). For biphasic, environmentally-friendly system (EtOAc-H2 O), see: Org. Process Res. Dev., 6, 407 (2002). Selective oxidation of phosphorus ylides occurs under mild conditions, providing a route to vicinal tricarbonyl derivatives: J. Org. Chem., 60, 8231 (1995). For conversion of ɑ-bromo-ß-dicarbonyls to vicinal tricarbonyls, see: Tetrahedron Lett., 36, 7735 (1995). For formation of singlet oxygen by deoxygenation of heteroaromatic N-oxides, e.g. 4-diethylaminopyridine N-oxide, see: J. Chem. Soc., Chem. Commun., 1831 (1995). For reviews of dioxiranes, see: Acc. Chem. Res., 22, 205 (1989); Chem. Rev., 89, 1187 (1989).
