Abstract
The title compound, C14H12O4, was prepared via alkylation of 4-hydroxy-3-methoxybenzoic acid with propargyl bromide in the presence of K2CO3.
The title compound, C14H12O4, comprises of two crystallographically independent molecules in the asymmetric unit, linked via C—H⋯O interactions to form dimeric entities. The allylic groups are twisted out of the phenyl planes with dihedral angles varying between 7.92 (13) and 25.42 (8)°. In the crystal, the packing follows a zigzag pattern along the c-axis direction. The absolute configuration of the sample could not be determined reliably.
