The balanced equation for trans-1,2-dibenzoylethylene in ethanol to give the product cis-1,2-dibenzoylethylene?
There are two reason why the enols of beta-dicarbonyl compounds, such as pentane-2,4-dione are relatively stable. One is that they are conjugated and the pi-electron overlap due to the conjugation provides additional stability.
