| Summary: | The compounds 2-(1-benzofuran-2-yl)-2-oxoethyl 2-nitrobenzoate, C17H11NO6 (I), and 2-(1-benzofuran-2-yl)-2-oxoethyl 2-aminobenzoate, C17H13NO4 (II),
were synthesized under mild conditions. Their molecular structures were
characterized by both spectroscopic and single-crystal X-ray diffraction analysis.
The molecular conformations of both title compounds are generally similar.
However, different ortho-substituted moieties at the phenyl ring of the two
compounds cause deviations in the torsion angles between the carbonyl group
and the attached phenyl ring. In compound (I), the ortho-nitrophenyl ring is
twisted away from the adjacent carbonyl group whereas in compound (II), the
ortho-aminophenyl ring is almost co-planar with the carbonyl group. In the
crystal of compound (I), two C 14H
