Hydrochloric Acid → Indane

Participants

Reaction Steps

A 400 mL reaction vessel fitted with a mechanical stirrer was charged with sorbitol (32 g, 0.18 mol), water (20 g), concentrated HCl (45 g) and dodecylbenzenesulfonic acid (0.4 g). After stirring for 10 min, 5-formylindan (29 g, 0.20 mol) was added. The mixture was stirred for 18 h, then neutralized with aqueous KOH. The solids were collected by filtration and washed with water and methanol to give Indan DBS as a white solid (14 g, 33% yield).
