摘要

The cis-and ths-dibenzoylmethylethylenes (VI and V) are converted readily into the bromofuran (VII) by hydrogen bromide in acetic acid, but it has not been possible under the experimental conditions to determine the relative ease of reaction in the two cases. In the reaction with acetic anhydride and sulfuric acid at room temperature, on the other hand, the trans-compound did not react whereas the cis-isomer was converted in good yield into the ...
