Two closely related 2-(benzo-furan-2-yl)-2-oxoethyl benzoates: structural differences and C-H⋯O hydrogen-bonded supra-molecular assemblies.

ABSTRACT: The compounds 2-(1-benzo-furan-2-yl)-2-oxoethyl 2-nitro-benzoate, C₁₇H₁₁NO₆ (I), and 2-(1-benzo-furan-2-yl)-2-oxoethyl 2-amino-benzoate, C₁₇H₁₃NO₄ (II), were synthesized under mild conditions. Their mol-ecular structures were characterized by both spectroscopic and single-crystal X-ray diffraction analysis. The mol-ecular 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-nitro-phenyl ring is twisted away from the adjacent carbonyl group whereas in compound (II), the ortho-amino-phenyl rin
