Versuchsvorschrift
To a solution of indane (50 mmol, 6.11 mL) in dichloromethane (50 ml) at 0° C. is added dropwise chlorosulfonic acid (200 mmol, 13.3 ml). The resulting solution is allowed to return to room temperature and is stirred for 2 hr. The solution is then poured slowly onto a mixture of ice (200 g) and dichloromethane (50 ml). The organic layer is separated, washed with brine (50 mL), dried over sodium sulfate, filtered and evaporated to produce indan-5-sulfonic acid chloride.
