Procedimiento

In a 300 ml three-necked flask, 2 g of tetrahydroxythiophene was dissolved in 20 ml of acetone. To the solution, 4.87 g of 1-bromo-3,3-dimethy 2-butanone was added dropwise while stirring. After leaving for 24 hours, the deposited white crystal was collected by filtration. The white crystal was ground to a powder, which was washed with ether. The powder was dried by a vacuum drier at 30° C. for six hours to obtain 5.15 g of 2-oxo-3,3-dimethylbutyl-thiacyclopentanium bromide (yield: 75.0%).
