1-bromo-2-methylsulfinylbenzene

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Oxone (9.7 g) in water (40 ml) was added slowly to a stirred, cooled cooled (0° C.) solution of 2-bromothioanisole (5 g, 24.6 mmol) and sodium bicarbonate (16 g) in acetone (20 ml). The mixture was stirred for at room temperature 16 h., then water and dichloromethane was added. The layers were separated and the organic phase was dried (MgSO4) and the solvent was evaporated under reduced pressure. The residue was purified by chromatography on silica gel, eluting with hexane/EtOAc (80:20 increasing to 40:60) to give the title compound (6.1 g). m/z (ES+) 219 (M+1). cooled The layers were separated the organic phase was dried (MgSO4) the solvent was evaporated under reduced pressure The residue was purified by chromatography on silica gel eluting with hexane/EtOAc (80:20 increasing to 40:60)
