Comparative studies on chlorination and methylation reactions have been carried out to afford chloromethyl(methyl)silanes. For chlorination reactions, three types of initiators, viz., azobisisobutyronitrile, benzoyl peroxide and dicumyl peroxide have been studied at different reaction conditions, e.g., solvent, temperature, time duration of reaction and molar ratio of reactants in view to get o...
The title complex, [Nd(C(15)H(11)O(2))(NO(3))(2)(C(18)H(15)N(3)O)]·CH(3)CN or [Nd(altpy)(dbm)(NO(3))(2)]·CH(3)CN (altpy = 4'-all-yl-oxy-2,2':6',2''-terpyridine, dbm = dibenzoyl-methanide anion), has been synthesized from 4'-all-yloxy-2,2':6',2''-terpyridine, dibenzoyl-methanate and neodymium nitrate. The Nd(3+) atom is nine-coordinated by two O atoms from the bidentate dbm ligand, three N atoms...
In the title compound, [U(C(15)H(11)O(2))(2)O(2)(C(2)H(6)O)], the U(VI )atom has a penta-gonal-bipyramidal coordination geometry. The two so-called '-yl' O atoms occupy the axial positions whereas four O atoms from the two chelating dibenzoyl-methanate ligands and the O atom from the ethanol mol-ecule are situated in the equatorial plane. Inter-molecular hydrogen bonds between one of the '-yl' ...
(4′-Allyloxy-2,2′:6′,2′′-terpyridine)(dibenzoylmethanido)dinitratoerbium(III) acetonitrile solvate
The title complex, [Er(C(15)H(11)O(2))(NO(3))(2)(C(18)H(15)N(3)O)]·CH(3)CN, has been synthesized from 4'-all-yloxy-2,2':6',2''-terpyridine (altpy), dibenzoyl-methane and erbium nitrate. The distorted monocapped square anti-prismatic coordination polyhedron is formed by a bidentate dibenzoyl-methanide residue, a tridentate altpy ligand and two nitrate anions that act as bidentate ligands and occ...
Superoxidized solution (SOS) is an electrochemically processed aqueous solution manufactured from pure water and sodium chloride. Inflammatory skin disorders have all improved their outcomes with the use of SOS. These indications point that SOS could be useful in acne. Forty patients were enrolled in this open label, clinical trial. Patients had present with 10-50 inflammatory lesions (papules ...
The title compound, C(15)H(13)Br(4)NO(4), was obtained via radical bromination reaction of ethyl 6,7-dimeth-oxy-2-methyl-quinoline-3-carboxyl-ate and N-bromo-succinimide (NBS) in the presence of benzoyl peroxide (BPO) under photocatalytic conditions. The quinoline ring system is approximately planar with a maximum deviation from the mean plane of 0.035 (1) Å. The dihedral angle between the six-...
In the present study, we describe the photochemical behaviour of 2-mesyloxy phenyl ketones 8 and 12 bearing a cyclopropane moiety in the side-chain. Irradiation of 8 and 12 leads to the corresponding benzoyl spiro[2.2]pentanes as a consequence of an initial gamma-H-shift, subsequent elimination of MsOH (accompanied by a spin-center shift) and cyclization of the resulting 1,3-diradicals. In cont...
We present some recent developments in the study of quark-hadron duality in structure functions in the resonance region. To understand the workings of local duality we introduce the concept of truncated moments, which are used to describe the Q dependence of specific resonance regions within a QCD framework.
OBJECTIVES To evaluate the effects of the anti-inflammatory hydroxystilbene, resveratrol, on Propionibacterium acnes growth. METHODS Three different strains of P. acnes were tested against resveratrol at concentrations between 0 and 200 mg/L. Piceatannol was included as a second hydroxystilbene to compare with resveratrol, and erythromycin and benzoyl peroxide were used as positive controls. ...
