In the title compound, [Re(3)(μ-H)(3)(C(25)H(22)P(2))(CO)(10)]·CH(2)Cl(2), the three Re atoms form a triangle bearing ten terminal carbonyl groups and three edge-bridging hydrides. The bis-(diphenyl-phosphan-yl)methane ligand bridges two Re atoms. Neglecting the Re-Re inter-actions, each Re atom is in a slightly distorted octa-hedral coordination environment. The dichloro-methane solvent mol-ec...
This paper presents experimental results and analyses on the controlled manipulation of a liquid droplet. The droplet was manipulated upon local reduction and oxidation (redox) of dodecylbenzenesulfonate doped polypyrrole (PPy(DBS)) in an immiscible organic fluid of bulk dichloromethane (DCM, CH(2)Cl(2)). The electrochemically tunable wetting property of PPy(DBS) permitted liquid droplet manipu...
The ladder-like structure of the tetranuclear title compound, [Sn(4)(C(6)H(5))(4)Cl(2)O(2)(OH)(2)(C(9)H(13)N)(2)(C(9)H(12)N)(2)]Cl(2)·10CDCl(3), consists of two five- and two six-coordinated Sn(IV) atoms bridged by oxide or hydroxide groups. The chelating ligands reveal rather strong Sn-N bonds [2.517 (4) Å], but the protonated dimethylamino groups in the periphery of the complex show no intera...
The self-recombination of the methylene amidogen radical (H(2)CN) is known to be fast and should play an important role in determining the concentration of H(2)CN radicals in both combustion and astrophysical processes. The rate constants of H(2)CN + H(2)CN have been determined by previous experiments, whereas its detailed evolution process and product distribution are still unclear. In this wo...
The dichloromethane extract of Calea uniflora afforded a mixture of two novel chromanones, uniflorol-A (1) and uniflorol-B (2), and one known chromanone, 2,2-dimethyl-6-(1-hydroxyethyl)-chroman-4-one (3). The structures of these compounds were determined by spectroscopic methods. Biological activity of the compounds against Leishmania major promastigotes was evaluated. Mixture of the novel chro...
A very simple and quick analytical method, based on direct aqueous injection, for determination of halogenated solvents in refinery water and wastewater, is described. There is a need to determine halogenated solvents in refinery water streams, because they may originate from several processes. There is also a need to develop methods enabling VOX to be determined in samples containing oil fract...
We demonstrated a simple and green chemical method to obtain Michael adducts and their derivatives by using GO as a phase transfer catalyst with different kinds of bases in water and dichloromethane, and we also used GO multiple cycles almost without reduction in reaction yields.
Novel [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) analogues containing benzo[b]thiophene (3a, 3b) and thieno[3,2-b]thiophene (3c, 3d) were synthesized and characterized. The morphology of the thin films prepared from the mixtures of these methanofullerenes with regioregular poly(3-hexylthiophene) (P3HT) was investigated by AFM measurement and UV-Vis absorption spectroscopy. A solubility t...
The biomimetic oxidation of etodolac, an anti-inflammatory drug (1) with iodosylbenzene catalyzed by 5,10,15,20-tetraarylporphyrinatoiron(III) chlorides TAPFe(III)Cl (7a-e) in dichloromethane gives 4-hydroxyetodolac (6) and 4-oxoetodolac (5) regioselectively in moderate yields.
