1-methyl-4-(3-methylbut-2-enylsulfonyl)benzene

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: In dimethylformamide (20 ml) was dissolved 1-bromo-3-methyl-butene(1.49 g, 10 m moles) and sodium p-toluenesulfinate dihydrate (2.5 g, 1.16 equiv.), the solution was stirred at room temperature for 3 hours. The product was isolated in the usual manner and recrystallized from n-hexane to give 1-(p-toluenesulfonyl)-3-methyl-2-butene (2.16 g, 96.4%), melting point: 71°-72° C. The product was isolated in the usual manner recrystallized from n-hexane
