Crystal structure of 2-(5-bromo-2-hydroxybenzylidene)-2,3-dihydro-1H-indene-1,3-dione
The title mol-ecule, C16H9BrO3, deviates slightly from planarity. The benzene ring makes a dihedral angle of 1.02 (9)° with the plane defined by the five-membered ring of the indandione moiety. The latter exhibits a minute twist indicated by the dihedral angle of 0.47 (9)° between the planes of the five- and six-membered rings. An intra-molecular C-H⋯O hydrogen bond between the attached benzene...
متن کاملAsymmetric synthesis of (7aS)-7a-methyl-4,5,7,7a-tetrahydro-1H-indene-2,6-dione and useful derivatives thereof.
The enantioselective synthesis of the title compound, using Meyers' bicyclic lactam methodology, is described. This compound and a few of its derivatives are useful intermediates in natural product synthesis.
متن کاملCrystal structure of 2-hydroxy-2-(2-oxocycloheptyl)-2,3-dihydro-1H-indene-1,3-dione
In the title compound, C16H16O4, the five-membered ring of the indene-1,3-dione unit adopts a twist conformation, whereas the seven-membered ring adopts a twist-chair conformation. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, weak C-H⋯O hydrogen bonds and π-π stacking [centroid-to-centroid distance = 3.7373 (8) Å] into a three-dimensional supra-molecular architecture.
متن کاملrac-2-Hydroxy-2-(2-oxocyclopentyl)-1H-indene-1,3(2H)-dione
In the title compound, C(14)H(12)O(4), the indene unit is essentially planar [r.m.s. deviation = 0.0309 (1) Å] and the cyclo-penta-none ring adopts a twist form. In the crystal, mol-ecules are joined via pairs of O-H⋯O hydrogen bonds into centrosymmetric dimers.
متن کاملRed electroluminescence of ruthenium sensitizer functionalized by sulfonate anchoring groups.
We have synthesized five novel Ru(ii) phenanthroline complexes with an additional aryl sulfonate ligating substituent at the 5-position [Ru(L)(bpy)2](BF4)2 (1), [Ru(L)(bpy)(SCN)2] (2), [Ru(L)3](BF4)2 (3), [Ru(L)2(bpy)](BF4)2 (4) and [Ru(L)(BPhen)(SCN)2] (5) (where L = 6-one-[1,10]phenanthroline-5-ylamino)-3-hydroxynaphthalene 1-sulfonic, bpy = 2,2'-bipyridine, BPhen = 4,7-diphenyl-1,10-phenanth...
