1,1′-(Ethane-1,2-diyl)bis(indoline-2,3-dione)
The mol-ecule of the title compound, C(18)H(12)N(2)O(4), is situated on a crystallographic centre of symmetry. The mol-ecule has a zigzag structure, with two parallel symmetry-related indoline-2,3-dione fragments linked by an ethyl-ene group at each N atom. In the crystal, the mol-ecules stack in columns along the b axis. There are two such columns in the structure. The mol-ecules within each c...

In the mol-ecule of the title compound, C(16)H(14)O(2), a substituted benzil, the dicarbonyl unit has an s-trans conformation. This conformation is substanti-ated by the O-C-C-O torsion angle of 108.16 (15)°. The dihedral angle between the two aromatic rings is 72.00 (6)°. In the crystal structure, neighbouring mol-ecules are linked together by weak inter-molecular C-H⋯O hydrogen bonds and weak...
متن کامل(E)-1,2-Bis(4-fluorophenyl)ethane-1,2-dione
The title compound, C(14)H(8)F(2)O(2), is a substituted benzil with an s-trans conformation of the dicarbonyl unit. This conformation is also shown by the O-C-C-O torsion angle of -110.65 (12)°. An unusual feature of the structure is the length, 1.536 (2) Å, of the central C-C bond connecting the carbonyl units, which is significantly longer than a normal Csp(2)-Csp(2) single bond. This is prob...
متن کامل1,2-Bis{2-[2-(trimethylsilyl)ethynyl]phenyl}ethane-1,2-dione
The title compound, C(24)H(26)O(2)Si(2), has C(2) crystallographic symmetry. The dihedral angle between the aromatic rings is 84.5 (2)°. The acetyl-ene group is slightly non-linear, with angles at the acetyl-ene C atoms of 175.7 (2) and 177.0 (2)°. In the crystal structure, only van de Waals interactions occur.

This is a report on a symposium sponsored by the American Society for Pharmacology and Experimental Therapeutics and held at the Experimental Biology 2012 meeting in San Diego, California, on April 25, 2012. The symposium speakers summarized and critically evaluated our current understanding of the physiologic, pharmacological, and toxicological roles of NADPH–cytochrome P450 oxidoreductase (PO...
