β¦ Synopsis
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 unimolecular reversible process.

## 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
The use of lithium and a catalytic amount of an arene is a well-established methodology for the preparation of organolithium reagents that manifest greater reactivity than the classical lithium-arene solutions. In order to rationalize this conduct, the participation of a highly reduced species, the
