摘要

In previous papers of this series benzylations of ketene diethylacetall (I) and various alkyl- and phenylketene dimethylacetals*(VII) with benzyl bromide were reported. In each of these alkylations the reaction proceeded to the formation of disubstituted acetic esters (VI and IX),;. e., the unsubstituted ketene acetal was dibenzylated, presumably through the intermediate ketene acetal IV (R= CaHsCH2), while the monosubstituted ketene acetals (VII, X is n- ...
