5-Nitro-1-benzofuran-2(3H)-one
In the crystal structure of the title compound, C(8)H(5)NO(4), essentially planar mol-ecules [largest deviation from the least-squares plane = 0.030 (2) Å] form stacks along the a-axis direction. Intercentroid separations between overlapping benzene rings within the stack are 3.6594 (12) Å and 3.8131 (12) Å. Mol-ecules from neighboring stacks are linked by weak C-H⋯O hydrogen bonds into inversi...
متن کامل3-(2-Methoxynaphthalen-1-yl)-2-benzofuran-1(3H)-one
The asymmetric unit of the title compound, C(19)H(14)O(3), contains two crystallographically independent mol-ecules in which the dihedral angles between the naphthalene and benzofuran ring systems are 76.49 (7) and 86.17 (7)°. In the crystal, mol-ecules are linked by inter-molecular C-H⋯O hydrogen-bonding inter-actions into chains running parallel to the a axis. In addition, the crystal packing...

6-Carbethoxy-5-(3'-bromophenyl)-3-aryl-2-cyclohexenones 2a-j were obtained from the1-Aryl-3-(3'-bromophenyl)-2-propene-1-ones 1a-j by Micheal addition of ethyl acetoacetate, followed by internal Claisen condensation. Reaction of 2a-j with hydrazine hydrate afforded the corresponding 6-Aryl-4-(3'-bromophenyl)-3-oxo-2,3a,4,5-tetrahydro-2H-indazoles 3a-j. The structures of newly synthesized compou...
متن کامل(Z)-2-(4-Nitrobenzylidene)-1-benzofuran-3(2H)-one
In the crystal structure of the title compound, C(15)H(9)NO(4), weak C-H⋯O inter-actions generate rings with R(2) (2)(8) motifs. The supra-molecular aggregation is completed by the presence of C-H⋯O and van der Waals inter-actions.
متن کامل2-(2-Hydroxypropan-2-yl)-6-(prop-2-ynyloxy)-1-benzofuran-3(2H)-one
In the title compound, C14H14O4, the prop-2-yn-yloxy O-C-C C plane [maximum deviation = 0.0116 (12) Å] forms a dihedral angle of 78.44 (9)° with the benzofuran-3(2H)-one ring system. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming a tape along the a-axis direction. C-H⋯O inter-actions are observed between the tapes.
