Stereochemistry of the thermal isomerizations of (1/R,2R)-1-((E)-Styryl)-2-methylcyclopropane to 3-phenyl-4-methylcyclopentenes

(1A,2R)-1-((E)-Styryl)-2-methylcyclopropane at 250 °C racemizes and isomerizes to 6-phenylhexa-1,4-(Z)-diene and to the four isomers of 3-phenyl-4-methylcyclopentene. From the measured rate constants for racemization and for structural isomerizations, and

The Influence of Intramolecular Dynamics on Branching Ratios in Thermal Rearrangements

1- and 2-phenylbicyclohex-2-enes-5-d undergo thermal rearrangement to give products, differing only in the location of the deuterium, in ratio of about 9:1, but with identical activation enthalphies.Similarly, opticallly active trans-2-methyl-1-(trans-2-phenylethenyl)cyclopropane is found to rearrange to enantiomeric methylphenylcyclopentenes that are formed in a 5.9:1 ratio but with virtually identicyl activation enthalphies.Barring repeated coincidence, these results do not seem to be explicable within the framework of statistical theories of unimolecular kinetics such as RRKM theory, transition state theory, and variational transition state theory.The possible influence of dynamic effects in these and other unimolecular reactions is discussed.
