Efficient halogen photoelimination from dibromo, dichloro and difluoro tellurophenes.
We present the reactivity and photochemistry of 2,5-diphenyltellurophene. A change in oxidation state from Te(ii) to Te(iv) occurs by oxidative addition of bromine, chlorine, and fluorine from appropriate halogen sources. Photoreductive halogen elimination is demonstrated using optical absorption spectroscopy and NMR spectroscopy. The photodebromination reaction occurs with 16.9% quantum yield,...
متن کامل{6,6′-Dibromo-4,4′-dichloro-2,2′-[o-phenylenebis(nitrilomethylidyne)]diphenolato}nickel(II)
In the title complex, [Ni(C(20)H(10)Br(2)Cl(2)N(2)O(2))], the Ni(II) ion is coordinated by two phen-oxy O atoms and two imino N atoms of the tetradentate ligand, forming a slightly distorted square-planar environment. The mol-ecule is essentially planar, with an r.m.s. deviation of 0.088 Å for the mean plane defined by all non-H atoms in the mol-ecule.

The title compound, C(15)H(10)Br(2)Cl(2)N(2), a 2,8-dibromo-4,10-dichloro Tröger's base analogue derived from 4-bromo-2-chloro-aniline, has a dihedral angle of 110.9 (10)° between the two aryl rings, the largest yet measured for a simple dibenzo analogue.
متن کامل2,3-Dibromo-1-(2,4-dichloro-5-fluorophenyl)-3-phenylpropan-1-one
In the title compound, C(15)H(9)Br(2)Cl(2)FO, the dihedral angle between the two aromatic rings is 6.0 (1)°. The dibromo-ethane fragment of the propan-1-one unit is disordered over two positions, with occupancies of ca 0.83 and 0.17. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds, C-H⋯π inter-actions, and Br⋯Cl [3.505 (2) and 3.576 (6) Å] and Cl⋯F [3.176 (2) Å] shor...
متن کاملC2nr11689h 1010..1015
Water-soluble carbon nanoparticles were prepared by refluxing natural gas soot in concentrated nitric acid. The surface of the resulting nanoparticles was found to be decorated with a variety of oxygenated species, as suggested by spectroscopic measurements. Back potentiometric titration of the nanoparticles was employed to quantify the coverage of carboxylic, lactonic, and phenolic moieties on...
