Ethyl 5-bromo-1-benzofuran-2-carboxylate

Abstract

In the title compound, C11H9BrO3, the benzofuran fused-ring system is almost planar, with a maximum atomic deviation of 0.024 (5) Å; the carboxyl -CO2 fragment is aligned at 4.8 (7)° with respect to the fused-ring plane. Weak intermolecular C - H⋯O hydrogen bonding is present in the crystal structure. π-π stacking is also observed between parallel molecules, the centroid-centroid distance between benzene and furan rings of adjacent molecules being 3.662 (3) Å.
