1-(5-Nitro-2-oxoindolin-3-ylidene)thiosemicarbazide
In the title molecule, C(9)H(7)N(5)O(3)S, there is an intramolecular N-H⋯O. The molecule is essentially planar, with the maximum deviation from the mean plane of the 18 non-H atoms being 0.135 (2) Å for the amine N atom. In the crystal, the molecules are connected via intermolecular N-H⋯O and N-H⋯S hydrogen bonds, forming two-dimensional networks lying parallel to (10[Formula: see text]). They ...
متن کاملA competitive Diels-Alder/1, 3-dipolar cycloaddition reaction of1-H-imidazole 3-oxide toward sulfonyl methane. A DFT study on the energetic and regioselectivity
The dual diene/1,3-dipolar character of 1-H-imidazole 3-oxide, HIO 1, allows this compound toparticipate in a competitive Diels-Alder (DA)/1,3-dipolar cycloaddition (13DC) reaction toward C=Sdouble bond of the electro-deficient sulfonyl methane SFM 2. The B3LYP/6-311++G(d,p) calculatedrelative Gibbs free energies indicate that among the studied 13DC and DA reactions, former iscompletely preferr...
متن کامل(Z)-2-(1-Benzyl-5-nitro-1H-indol-3-ylmethylene)-1-azabicyclo[2.2.2]octan-3-one.
In view of the biological activity associated with 1-azabicyclo[2.2.2]octan-3-ones, we have undertaken the synthesis and structural analysis of a series of 2-(substituted benzylidene/heteroaryl-3-ylmethylene)-1-azabicyclo[2.2.2]octan-3ones (Sonar et al., 2003). In order to con®rm the double-bond geometry of title compound, (I), and to obtain more detailed information on the structural conformat...
متن کامل5-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...
