Procedure
Sodium metaperiodate (4.1 g, 0.019 mole) was dissolved in 40 ml of water and cooled in an ice bath. 3-Butyltetramethylene sulfide (2.62 g, 0.018 mole) was added and the reaction mixture was stirred at 0° overnight. The NaIO3 which precipitated during the reaction was removed by filtration, and the filtrate was extracted with two 40-ml portions of chloroform. The extract was dried over anhydrous MgSO4, and the solvent was removed under reduced pressure. Vacuum distillation yielded 1.8 g (62%) of 3-butyltetramethylene sulfoxide: b.p. 95° C. C/0.52 mm. Anal. Calcd. for C8H16SO; C, 59.95, H, 10.06; S, 20.00. Found: C, 59.78; H, 10.05, S, 1972%. The NMR spectrum is consistent with the structure for 3-butyltetramethylene sulfoxide.
