Versuchsvorschrift

Anhydrous hydrogenchloride gas is bubbled through spiro(cyclopentane-1,1'-indene) (117.5 g; 0.69 moles) until 25 g have absorbed. The temperature is held under +10° C. by cooling on an ice bath. The liquid obtained is distilled and at first a small amount of unreacted spiro-cyclopentaneindene passes over, followed by about 135 g (Yield 95%) 3'-chlorospiro(cyclopentane-1,1'-indan) bp 97° C./0.7 mm Hg. nD20 =1.5625.
