Rhodium-catalyzed carbonylative arylation of alkynes with arylboronic acids: An efficient and straightforward method in the synthesis of 5-aryl-2(5H)-furanones
(Royal Society of Chemistry, 2006)
5-Aryl-2(5H)-furanones can be synthesized by the Rh-catalyzed reactions of arylboronic acids with internal alkynes under a CO atmosphere.
Controlled Formation of the Two-Dimensional TTBC J-Aggregates in an Aqueous Solution
(American Chemical Society, 2013-09-30)
Strong experimental and theoretical evidence was provided on the controlled formation of the two-dimensional J-aggregates that were assembled in the herringbone morphology. The exciton-band structure formation of ...
Speciation and preconcentration of inorganic tellurium from waters using a mercaptosilica microcolumn and determination by hydride generation atomic absorption spectrometry
(Royal Society of Chemistry, 2000-11-23)
A separation–preconcentration method utilising a mercapto-modified silica microcolumn was developed for the determination of trace amounts of Te(IV) and Te(VI) in waters by hydride generation atomic absorption spectrometry. ...
Optical transition rates of a meso-substituted thiacarbocyanine in methanol-in-oil reverse micelles
We report the photophysical properties of 3,3′-diethyl-5,5′-dichloro-9-phenylthiacarbocyanine (DDPT) in methanol-in-oil (m/o) reverse micellar systems which form methanol droplets stabilized with anionic surfactant aerosol-OT ...
A BODIPY-based reactive probe for the detection of Au(iii) species and its application to cell imaging
(Royal Society of Chemistry, 2014-06)
A BODIPY-based fluorescent probe bearing a pyridyl hydrazone motif responds selectively to Au(III) ions through an irreversible C[double bond, length as m-dash]N bond hydrolysis reaction. Gold species, besides their ...
Regio- and stereoselective synthesis of 2,3,5-trienoates by palladium-catalyzed alkoxycarbonylation of conjugated enyne carbonates
(American Chemical Society, 2014-10)
Palladium-catalyzed carbonylation of 2,4-enyne carbonates in an alcohol and under balloon pressure of CO proceeds through 1,5-substitution to yield (E)-2,3,5-trienoates. The olefin geometry of the substrate is important ...
A guanidinium modified rhodamine-based fluorescent probe for in vitro/vivo imaging of gold ions
(Royal Society of Chemistry, 2015-10-07)
We devised a rhodamine-based fluorescent probe functionalized with a guanidinium moiety, which both operates efficiently in pure aqueous media and displays a selective fluorescence response to Au3+ ions. We also demonstrated ...
Integration of triboluminescent EuD4TEA crystals to transparent polymers: Impact sensor application
(American Chemical Society, 2017-02)
Lanthanide-based organometallic materials are well-known candidate triboluminescent (TL) materials that can show bright emission when a mechanical force is applied. These materials are usually in the form of crystalline ...
Synthesis and anticancer activity evaluation of new isoindole analogues
We have developed a versatile synthetic approach for the synthesis of new isoindole derivatives via the cleavage of ethers from tricyclic imide skeleton compounds. An exo-cycloadduct prepared from the Diels–Alder reaction ...
Iron-promoted 1,5-substitution (SN2′′) reactions of enyne acetates and oxiranes with Grignard reagents
Acetate derivatives of 2-en-4-yne alcohols 1 and enyne oxiranes 4 regioselectively underwent 1,5-substitution (SN2′′) reactions with Grignard reagents in the presence of an iron compound to provide vinylallenes exclusively ...
