Abstract

(E)-1, 2-bis (trans-2, trans-3-diphenylcyclopropyI) ethene, and also (a-1, 2-bis (trans-2, trans- 3-diphenylcyclopropyl) ethene. The influence of electronic and steric factors in determining the second-order rate constants (k,) for the reactions of trans-alkenes with (Br8TPP) CrV (0)(X) were separated by use of the linear free-energy relationship of log k, and the one- electron oxidation potentials (El $ established by the reaction of a series of cis-alkenes ...
