Diethyl Ethoxymethylenemalonate

Sodium azide reacts with diethyl ethoxymethylenemalonate in dimethylsulfoxide to give diethyl 2,4-diethoxycarbonylpent-2-enedioate (12%) and diethyl 5-hydroxypyrrole-2,4-dicarboxyiate (60%). The structure of the latter was determined by X-ray crystal structure analysis at 150 K, and both compounds have been independently synthesized.

The title compound, C14H11BrO, was synthesized by the reaction of 4-methylbenzophenone and bromine in carbon tetrachloride. X-ray crystal structure analysis reveals that the benzene and phenyl rings form a dihedral angle of 59.53 (6)°, and the crystal packing is stabilized by intermolecular C—H...π interactions.
