Abstract:(1 R, 2R)-1-((E)-Styryl)-2-methylcyclopropane at 250 OC racemizes and isomerizes to 6-phenylhexa-1, 4-(Z)-diene and to the four isomers of 3-phenyl-4-methylcyclopentene. From the measured rateconstants for racemization and for structural isomerizations, and from information on the relative amounts of the four 3-phenyl-4-methylcyclopentenes as a function of time, the relative contributions of the four stereochemically distinct paths for this ...
