The next step in our systematic examination of the radical cationinitiated dimerization of plant monomers from the D{sub 6}-C{sub 3} pool of shikimic acid metabolites was to study the dimerization of cinnamic acid and its derivatives. In order to do this we needed a radical cation initiator that has a reduction potential greater than that of BAHA (E{sub red} = 1.30 volts), since the electron-withdrawing carboxylate functional group of cinnamates renders them inert to oxidation with BAHA. This problem was solved with the observation that DBAHA tris-(2,4-dibromophenyl)aminium hexachloroantimonate, E{sub red} = 1.74 volts, intiated the radical cation dimerization of methyl 3,4-dimethoxycinnamate.
