(Z)-2-(4-chloro-5h-1,2,3-dithiazol-5-ylideneamino)-6-ethoxy-4-phenylpyridine-3,5-dicarbonitrile
(2010)
2-Amino-6-ethoxy-4-phenylpyridine-3,5-dicarbonitrile 1 reacts with 4,5-dichloro-1,2,3-dithiazolium chloride 2 in the presence of pyridine (2 equiv.) to afford (Z)-2-(4-chloro-5H-1,2,3-dithiazol-5-ylideneamino)-6-ethoxy-4 ...
Alternating amphiphilic multiblock copolymers: Controlled synthesis via RAFT polymerization and aqueous solution characterization
(2010)
Four linear amphiphilic multiblock copolymers based on 2-(dimethylamino) ethyl methacrylate (DMAEMA, hydrophilic) and methyl methacrylate (MMA, hydrophobic), bearing from two to five blocks, were synthesized using reversible ...
Competitive sorption of Cu(II), Eu(III) and U(VI) ions on dunite in aqueous solutions: A potentiometric study
(2010)
The competitive sorption of Cu(II), Eu(III) and U(VI)) ions in aqueous solutions by dunite, has been investigated by potentiometry at pH 6, I = 0.1 M NaClO4 and 25°C. Numerical analysis of the experimental data supports ...
Competitive sorption of Cu(II) and Eu(III) ions on olive-cake carbon in aqueous solutions - A potentiometric study
(2010)
The competitive sorption of Cu(II) and Eu(III) ions from aqueous solutions by olive-cake carbon, has been investigated by potentiometry at pH 6, I = 0.1 M NaClO4, 25°C and under normal atmospheric conditions. Evaluation ...
Stabilization of lead sulfide nanoparticles by polyamines in aqueous solutions. A structural study of the dispersions
(2010)
Lead sulfide (PbS) nanoparticles have been synthesized in aqueous solutions by a reaction between inorganic lead salts and sodium sulfide and stabilized using the cationic polyelectrolytes branched poly(ethylenimine) (PEI), ...
Two-step total syntheses of Canthin-6-one alkaloids: New one-pot sequential Pd-catalyzed Suzuki-Miyaura coupling and Cu-catalyzed amidation reaction
(2010)
"Chemical Equation Presented" Canthin-6-one (1) and nine analogues including the naturally occurring 9-methoxycanthin-6-one (2) and amaroridine (3) are prepared rapidly and in high yields via a convergent "non-classical" ...
Charge-transfer excitons in strongly coupled organic semiconductors
(2010)
Time-resolved and temperature-dependent photoluminescence measurements on one-dimensional sexithiophene lattices reveal intrinsic branching of photoexcitations to two distinct species: self-trapped excitons and dark ...
Tricyclo[3.3.1.03,7]nonane-3,7-diyl bis(methanesulfonate)
(2010)
The crystal structure of the title compound, C11H 18O6S2, was determined to investigate the effect of the eclipsed mesyl groups on the bond length of the vicinal quaternary C atoms. The two quaternary C atoms of the ...
Well-defined polymers from biosourced monomers: The case of 2-(methacryloyloxy)ethyl tiglate
(2010)
Tiglic acid esters are naturally derived olefins of pleasant odor but incapable of undergoing free-radical polymerization due to the steric hindrances conferred by the β-methyl group. In an effort to incorporate these green ...
Synthesis, solution, and structural characterization of tetrahydrofuranyl-2,2-bisphosphonic acid disodium salt
(2010)
Bisphosphonates are biologically relevant therapeutics for bone disorders and cancer. Reaction of γ-chlorobutyric acid, phosphorus acid, and phosphorus trichloride without the use of solvent gave the tetrahydrofuranyl-2, ...
