Abstract
[3112-85-4] C7H8O2S (MW 156.22) InChI = 1S/C7H8O2S/c1-10(8,9)7-5-3-2-4-6-7/h2-6H,1H3 InChIKey = JCDWETOKTFWTHA-UHFFFAOYSA-N (generally used as the lithiated form, which reacts with a variety of electrophiles1) Physical Data: mp 86–88 °C. Solubility: sol ethanol, benzene. Form Supplied in: white solid; widely available. [13C]Methyl phenyl sulfone is also available. Preparative Method: by the reaction of Sodium Benzenesulfinate with Dimethyl Sulfate; by oxidation of methyl phenyl sulfide with 30% Hydrogen Peroxide in acetic acid; or by the reaction of polymer-supported benzenesulfinate anion with Iodomethane in refluxing benzene.2 Purification: recrystallized from carbon tetrachloride and 1∶3 ethanol–water. On a small scale, water is convenient for recrystallization.3
