Enantiomerically pure C16-alkyl amides derived from cis and trans cycloalkane-1,2-dicarboxylic acids, resp., have been synthesized and their behavior as organogelators has been investigated. These compounds include cis/trans diastereomeric cyclobutane and cyclohexane derivatives with the aim to explore the influence of the ring size as well as the relative configuration in their hierarchical self-assembly to form gels. High resolution 1H NMR spectroscopy studies allowed the determination of the dynamics of the gelation process in [D8]toluene and the sol-gel transition temperature The morphol. and size of the aggregates have been investigated and results have shown that, in the case of cyclobutane derivatives, the cis/trans stereochem. is not relevant for the gelation behavior and the properties of the soft-materials obtained, but it is remarkable for cyclohexane diamides, which are better organogelators. The four compounds produce chiral aggregates despite that two of them are meso achiral mols. We show herein that this fact is an example of stochastic symmetry breaking induced by sonication. The self-assembly of these mols. has been modelled providing information and support about the structure and the chirality of the aggregates.

Photoelectrochem. (PEC) measurements reveal that the compounds demonstrate photoresponse upon illumination by light of intensities 1000 and 10000 W/m2. The photoconductivity behavior of the derivatives I is enhanced in the presence of electron donor groups attached to the aromatic ring. Thereby, these products may be used in material devices as organic thin film transistors, on/off sensors, etc. The antioxidant activity of the products has been tested by DPPH radical scavenging method in vitro, indicating their significant potential. Antimicrobial activity of the derivatives I has been estimated by min. inhibitory concentration (MIC, mg/mL) using the micro-broth dilution method. The compounds are moderately active against some Gram pos. bacteria and Candida albicans and completely inactive against Gram neg. bacteria tested.

A simple “”turn-on”” fluorescent probe L was synthesized by condensation of furan-2-carbohydrazide and 2-hydroxy-4-methoxybenzaldehyde, and its structure was confirmed by single crystal X-ray diffraction. The probe L exhibited excellent selectivity towards Al3+ over other coexistent metal ions with remarkable fluorescence enhancement, accompanied by color change from colorless to blue. Moreover, the probe L showed high sensitivity to Al3+ with low detection limit (3.10 x 10-8 M) in the pH range of 3.0-8.0. The possible sensing mechanisms of L toward Al3+ were determined by Job plots experiments, high resolution mass spectrometry (HRMS), 1H NMR spectra and the d. functional theory (DFT) calculations Addnl., the probe L was successfully applied for detection of Al3+ in water samples with satisfactory results.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2-Furoic hydrazide, is researched, Molecular C5H6N2O2, CAS is 3326-71-4, about Ruthenium-Catalyzed Three-Component Alkylation: A Tandem Approach to the Synthesis of Nonsymmetric N,N-Dialkyl Acyl Hydrazides with Alcohols.Quality Control of 2-Furoic hydrazide.

The borrowing hydrogen strategy has been applied in the synthesis of nonsym. N,N-dialkylated acyl hydrazides via a tandem three-component reaction catalyzed by a phosphine free diaminocyclopentadienone ruthenium tricarbonyl complex. This strategy represents the first direct one-pot approach to nonsym. functionalized acyl hydrazides. Different aromatic acyl hydrazides underwent dialkylation with a variety of primary or secondary alcs. and methanol or ethanol as alkylating agents in mild reaction conditions and good yields. Deuterium labeling experiments suggested that the primary or secondary alc. was the hydrogen source in this tandem process. DFT calculations show that the combination of the tandem mixed product cannot be perfectly explained neither structurally nor electronically, but might be dependent of the phys. state of the aldehyde or ketone intermediate (gaz vs. liquid) at the reaction temperature

A series of Schiff base ligands as benzylidene benzohydrazide and their hydrazone analogs (Ia-Ic) have been synthesized and then complexed with organotin(IV) moiety having general formula [R’3SnL] to get the target compounds (1-9), where L = C4H3OCONHN:CHR, R = C6H5O (Ia), C4H5O (Ib), C6H3Cl2 (Ic) and R’ = -CH3 (1-3), -CH2Ph (4-6), -Ph (7-9). They were fully characterized using FT-IR, NMR (1H, 13C and 119Sn) spectroscopy, along with elemental anal. and m.p. One of the precursor (Ib) has been analyzed by single crystal XRD to further authenticate the structure. The 119Sn NMR data suggest the mol. geometry of organotin derivatives as distorted pentagonal bipyramidal. They were also evaluated for their antibacterial, antifungal, α-amylase inhibition, DPPH, total reducing power and total antioxidant activities. Triaryltin(IV) derivatives show good antibacterial and antifungal activity. Whereas the data for antidiabetic activity demonstrated that the compounds may serve as moderately effective alpha amylase inhibitor.
