Abstract

The decarboxylation of monodeuterated maleic acid monomethyl ester (DOOCCH=CHCOOCH3) in the presence of pyridine and quinoline was studied. The quantitative determination of the extent of deuterium incorporation in the resulting acrylic acid methyl ester shows that it is probable that in both cases decarboxylation occurs via the fragmentation of a betaine. The results conform with the assumptions made with earlier experiments.
