  • A study on the mechanism and scope of the radical-mediated oxidation of arylacetoacetates
    作者:Mercè Tona、Marisa Guardiola、Lluis Fajarí、Angel Messeguer
    DOI:10.1016/0040-4020(95)00576-t
    日期:1995.1
    Arylacetoacetate 1a undergoes an oxidative degradation in the presence of K(t)BuO, THF, catalytic I-2 and O-2, to give keto ester 4 as major compound. Hydrolysis and decarboxylation of this intermediate led to the corresponding arylcarboxylic acid 3a in satisfactory overall yields. By experiments conducted in the presence of O-18(2), incorporation of atmosphere oxygen into the benzylic position of 4 was evidenced. Furthermore, spin-trap experiments showed that benzyl radical 7 was generated in the reaction medium, which supports its role as intermediate in the pathway leading to the observed oxidation products. A plausible mechanism for this process is presented. On the other hand, appropriate conditions for achieving the alkylation of these arylacetoacetates with no concomitant formation of oxidation side-products are reported. Finally, arylacetates suffer also this degradative oxidation process leading to the corresponding arylcarboxylic acids without isolation of the intermediate keto ester derivative.
