Abstract
Racemisation rates for the indenes (1) provide migratory aptitudes for acyl, vinyl, ethynyl, nitrile, and alkyl groups, as well as hydrogen; it is proposed that the fast migration of formyl, acetyl, and benzoyl groups is, at least in part, due to a secondary interaction involving the carbonyl π* orbital.Keywords
