Abstract

Three propenoidic phenols, E-methyl ferulate, E-4-hydroxycinnamic acid methyl ester and E-3-chloro-4-hydroxycinnamic acid methyl ester, were oxidized with dioxygen, in the presence of N,N'-ethylenebis(salicylideneiminato)cobalt(II) [Cosalen]. The yields of conversion to oxidized products depended on the reaction solvent and on the substituents on the phenyl ring. EPR and electronic investigations suggest that an organometallic radical acts as the intermediate active species.
