Ethyl 5-bromo-1-benzofuran-2-carboxyl-ate. 2011

Hatem A Abdel-Aziz, and Ahmed Bari, and Seik Weng Ng

In the title compound, C(11)H(9)BrO(3), the benzofuran fused-ring system is almost planar, with a maximum atomic deviation of 0.024 (5) Å; the carboxyl -CO(2) fragment is aligned at 4.8 (7)° with respect to the fused-ring plane. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure. π-π stacking is also observed between parallel mol-ecules, the centroid-centroid distance between benzene and furan rings of adjacent mol-ecules being 3.662 (3) Å.
