Unimolecular isomerisation of hexa-1,trans-3,5-triene and symmetry-forbidden pyrolysis of cyclohexa-1,3-diene
Abstract
Arrhenius parameters are reported for the thermal isomerisation of hexa-1,trans-3,5-triene to the cis-compound and for the unimolecular decomposition of cyclohexa-1,3-diene to benzene and hydrogen which is symmetry-forbidden as a direct concerted process and proceeds via cyclohexa-1,4-diene.
