Abstract

The NMR spectra of 2-indanol and its acetate indicate that the cyclopentane ring is non-planar and that the substituent group adopts a pseudo-equatorial position. The cyclopentene ring in cis-tricarbonyl(2-indanol)chromium (II, R OH) and its acetate (II, R OAc) appears to be even more distorted but almost planar in the corresponding trans-compounds. No evidence could be found for strong intramolecular hydrogen bonds in the cis-alcohol compound. The spectra of methyl 2-indanecarboxylate and its carbonylchromium complexes are also discussed. Relative signs of coupling constants in the five-membered ring have been determined.
