✦ Synopsis

Due to homoconjugative interactions 2,3-dihydro-l,'l'-spirobiindene and 'l,l'-spirobiindene yield isomeric benzofluorenes in thermal, photochemical, and electron transfer induced rearrangement. Recently it was shown that the electron transfer induced rearrangement of l,ldisubstituted indenes proceeds by a dianion', following a concerted, suprafacial pathway2. &' ;z;:_ &'p.5lshift* &z]'

## Abstract __Ab initio__ molecular‐orbital theory has been used to study the 1,3‐sigmatropic hydrogen rearrangements: propene → propene, formic acic → formic acid, and vinyl alcohol → acetaldehyde. Fully optimized structures of stable molecules and transition states have been determined using grad
