2-Amino-4-(2-chlorophenyl)-5,10-dioxo-5,10-dihydro-4H-benzo[g]chromene-3-carbonitrile
In the mol-ecule of the title compound, C(20)H(11)ClN(2)O(3), the pyran ring adopts a flattened-boat conformation. In the crystal structure, inter-molecular N-H⋯N and N-H⋯O hydrogen bonds generate edge-fused R(2) (2)(12) and R(2) (2)(14) ring motifs; the hydrogen-bonded motifs are linked to each other, forming a three-dimensional network. A π-π contact [centroid-to-centroid distance = 3.879 (3)...

The title compound, C(16)H(10)N(2)O(5)S, was synthesized via the condesation of dihydro-thio-phen-3(2H)-one 1,1-dioxide, 1H-indene-1,2,3-trione and malononitrile in ethanol. The 2,3-dihydro-thio-phene 1,1-dioxide and pyran rings adopt envelope conformations. The mean planes through the planar part of the pyran ring and the benzene ring are nearly perpendicular, forming a dihedral angle of 88.40...

In the title compound, C(15)H(11)N(3)O(4)S, the dihedral angle between the mean planes of the dihydro-indol-2-one (r.m.s. deviation = 0.015 Å) and dihydro-thieno[3,2-b]pyran (r.m.s. deviation = 0.011 Å) ring systems is 89.53 (3)°. The crytal packing is consolidated by inter-molecular N-H⋯O and N-H⋯N hydrogen bonds, which link the mol-ecules into a two-dimensional network into sheets lying paral...

Moreover, electrolysis is done in CH3CN as solvent, Te...
متن کامل4-Dimethylamino-1-(4-methoxyphenyl)-2,5-dioxo-2,5-dihydro-1H-pyrrole-3-carbonitrile
In the title compound, C14H13N3O3, a twist occurs, as seen in the dihedral angle of 53.60 (12)° between the pyrrole and benzene rings. A three-dimensional architecture is formed in the crystal whereby layers of mol-ecules in the ac plane are connected by C-H⋯O and C-H⋯π inter-actions.
