The title reaction is suggested to proceed by a reversible valence isomerization via a laterally bridge benzvalene (2). No analogous behaviour is expected for pyrene. ## cc-13C-naphthalene (1') is known to rearrange thermally into 8-13C-naphthalene (1") following a rate law in accordance with an
## Abstract The thermal isomerization of [1,4βD~2~]β (3a) and [1,2β^13^C~2~]benzene (1a) has been studied in excess hydrogen at 750β850Β°C with contact time less than 1.2 s and very low partial pressure in a quartz flow system. In both cases, the main isomerization products are the corresponding __m
Despite the high level of interest accorded in recent years to those degenerate thermal iscnkerizations which involve only n electrons or a blend of Q and i electrons, automerization reactions of molecules constructed entirely of o bonds have been given little attention.
