Vorschrift
Isobutylene was bubbled through 75% H2SO4 solution at-5 degrees C. until 2.65 g (47.2 mmol) of isobutylene had been absorbed. The mixture was treated with 3.8 g (20.1 mmol) of 3-bromothiophenol and then allowed to warm to room temperature and stirred for 72 hours. The reaction mixture was then poured into 40 ml of an ice/water mixture and then extracted with ether. The ether extracts were combined and washed successively with 5% NaOH, water and saturated NaCl solution and then dried (MGSO4) The solvent was removed in-vacuo and the residue distilled (69-75 degrees C., 0.6 mm) to give the title compound as a pale yellow oil.
