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.
