Abstract:

2,5-Dicarboxy-2,5-dihydrofurans are key constituents of a number of natural products and have roles as intermediates in the formation of other such compounds of interest. Typically, these species are synthesized using toxic Pb(IV) salts. Electrochemical syntheses of 2,5-diacetoxy-2,5-dihydrofuran that do not require the use of lead have been reported, but a general lack of experimental detail has prevented these procedures from being more widely adopted. Moreover, no electrochemical study has yet reported the ratio of cis and trans isomers produced. Herein, we compare the chemical, lead-based route to 2,5-diacetoxy-2,5-dihydrofuran with a fully described electrosynthesis method. In doing so, we have discovered that the cis and trans isomers of this compound were previously incorrectly assigned in the literature, an error that we correct by obtaining the crystal structure of cis- 2,5-diacetoxy-2,5-dihydrofuran. This allows the ratios of the isomers as prepared by the chemical (2 : 1 cis : trans ) and electrochemical (7 : 5 cis : trans ) methods to be obtained. Through experimental and computational insights, we propose a mechanism for the electrochemical synthesis of 2,5-dicarboxy-2,5-dihydrofurans and go some way towards validating this mechanism by synthesizing 2,5-dibutoxy-2,5-dihydrofuran electrochemically for the first time. We hope that these findings will provide some greater clarity to the literature surrounding the electrosynthesis and potential applications of 2,5-dicarboxy-2,5-dihydrofurans.

Full text

Abstract:

A simple method was developed for determining microquantities of diltiazem, based on the reduction of copper(II) in buffered solution (pH 7.0) and the use of a micellar medium containing 4,4′-dicarboxy-2,2′-biquinoline acid. The copper(I) produced reacts with 4,4′-dicarboxy-2,2′-biquinoline acid and the complexes formed are spectrophotometrically measured at 558 nm. A typical calibration graph shows good linearity (r = 0.993) from 20 to 100 μg mL–1 of diltiazem. The limit of detection and relative standard deviation were calculated as 12 μg mL–1 (99% confidence level) and 3.5% (40 μg mL–1; n = 6), respectively, with a mean recovery value of 96.5% found in pharmaceutical dosages. A straightforward and effective way to recycle the reagents is addressed. The hazardous aspects of the Cu(I)–BCA reaction are presented as well.

Full text

Abstract:

Using a two-step oxidation of pectic acid (85% of D-galacturonan in the preparation) a series of 2,3-dicarboxy derivatives (Na+ form) was prepared containing 4.2 to 8.5 mmol of carboxyl groups per gram (COOH g-1). After the centrifugation of the diluted suspensions of the Ca-salts of these polyacids the activity of the calcium counterions (aCa2+) was determined using the metallochromic indicator (tetramethylmurexide) and the activity coefficient γCa2+ was calculated. Using potentiometric titrations of polyacids with potassium and calcium hydroxides the decrease in electrostatic free enthalpy, Δ(Gel/N)KCa, of the cation exchange Ca2+ → 2 K+ was determined. In the course of the oxidation, degradation of the macromolecules took place, characterized by the limit viscosity number [η]. In spite of the considerable degradation, preparations with higher oxidation degrees display a high selectivity in the exchange of cations Ca2+ → 2 K+, similar to that determined recently by us in 2,3-dicarboxy derivatives of starch and amylose. The strong binding of Ca2+ ions to the investigated substances is also documented by very low activity coefficient values, γCa2+, ranging from 0.057 to 0.037.

Abstract:

Acid-catalyzed cyclization of dimethyl 2,6-dimethyl-4-[(2-ethenyl-5-methoxy)phenyl]-1,4-dihydropyridine-3,5-dicarboxy-late affords novel products via competing intramolecular processes. The present mechanistic pathways differ from previous iminium ion-mediated cycloadditions, to afford conformationally constrained dihydropyridine analogs for study as calcium antagonists. These results illustrate the ability of the dihydropyridine nucleus to function as either a nucleophile or an electrophile, depending upon substituents in the aryl ring.

Transesterification occurred when the reaction was carried out in pentanol. Treatment of the palladium complex with sodium ethoxide at room temperature and further acidification resulted with tetra(1,2-dicarboxyethyl)phthalocyaninatopal-ladium. Its UV-vis spectrum in aqueous solution indicated dimeric and monomeric species at pH ≈ 12, but at pH ≈ 6 only the dimeric form were present.

Abstract New complex [RuL(Dmdcbp)2]PF6 (I) is synthesized by the consecutive reactions of [Ru-p-cymene]2Cl4 with 3,3',5,5'-tetramethyl-1,1'-biphenyl-4,4'-bipyrazole (L) and 4,4'-dicarboxy-2,2'-bipyridine in a methanol–chloroform medium. The composition of complex I is confirmed by NMR and elemental analysis, and the optical and luminescence properties of the complex are studied. Ligand L is characterized for the first time by X-ray diffraction (CIF file CCDC no. 2118676). Quantum chemical calculations in terms of the density functional theory are performed for the interpretation of the absorption and emission spectra. Complex I is promising for using as a photosensitizer.

Abstract:

Though 2-arylperimidines have never been used in iridium(III) chemistry, the present study on structural, electronic and optical properties of N-unsubstituted and N-methylated 2-(2-thienyl)perimidines, supported by DFT/TDDFT calculations, has shown that these ligands are promising candidates for construction of light-harvesting iridium(III) complexes. In contrast to N-H perimidine, the N-methylated ligand gave the expected cyclometalated μ-chloro-bridged iridium(III) dimer which was readily converted to a cationic heteroleptic complex with 4,4′-dicarboxy-2,2′-bipyridine. The resulting iridium(III) dye exhibited panchromatic absorption up to 1000 nm and was tested in a dye-sensitized solar cell.

Abstract:

Abstract. Cis-di(thiocyanato)-bis(4,4'-dicarboxy-2,2'-bipyridine) ruthenium(II) (N3) has been used as the standard complex in the dye-sensitized solar cells (DSSCs). This research studies the N3s which are commercial (N3-1) and synthesized (N3-2 to N3-5) in DSSC as the dyes sensitizer. We found that the varied power efficiencies were observed from 4.54 to 5.92%. The TGA and FT-IR techniques were employed to measure the small molecules that cannot identify by NMR spectra. The results clearly seen that the N3s have a different content in water and methanol residuals which affect the N3s solubility leading to the varied performance in DSSCs.

Abstract:

A series of novel aromatic polyamides containing 4-(dimethylamino)triphenylamine were prepared via the polycondensation reactions of the newly synthesized dicarboxylic acid, 4,4′-dicarboxy-4″-(dimethylamino)triphenylamine, and various diamines. Introduction of 4-(dimethylamino)triphenylamine units along the polymer chain enhanced the solubility of the polymers. The 10% weight loss temperatures of these polymers ranged from 432°C to 471°C with the char yields more than 63% at 800°C under nitrogen atmosphere. The polymers displayed low oxidation potentials because of the incorporation of dimethylamino at the para position of triphenylamine. Cyclic voltammograms of the polyamide films showed their onset potential around 0.38–0.47 V with color changing from nearly colorless to light blue.

Abstract:

We are investigating the properties of corrole-sensitized TiO 2 solar cells. The TiO 2-adsorbed free base and Ga III corroles display cell efficiencies under AM 1.5 illumination that are about half that of a standard N 3-sensitized cell ( N 3 = cis-bis(4,4'-dicarboxy-2,2'-bipyridine)dithiocyanato ruthenium(II)), while that of the Sn IV-based cell is much lower. The properties of the corrole- TiO 2 solar cells, along with results obtained with electrodes of lower conduction band energies clearly reveal that the reducing power of the singlet excited states of the free base and Ga III corrole, but not of the Sn IV derivative, is sufficiently high for efficient injection into the TiO 2 conduction band.
