F. Minassian et al., Rearrangements in the 11-thia-9,10-dihydro-9,10-ethanoanthracene series. Synthesis of a bridged thienooxepin, J CHEM R-S, (2), 1999, pp. 166-167
A rearrangement from 11-thia-9,10-dihydro-9,10-ethanoanthracene derivatives
into a thienooxepin is reported; the structure of the bridged oxepin is co
nfirmed by X-ray analysis.
