Prop-2-ynyl 3-methoxy-4-(prop-2-ynyloxy)benzoate

Abstract

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.
