We reported an efficient one-pot two-step synthesis of 3-(tert-butyl)-N-(4-methoxybenzyl)-1-methyl-1H-pyrazol-5-amine 3 in good yield by a solvent-free condensation/reduction reaction sequence starting from 3-(tert-butyl)-1-methyl-1H-pyrazol-5-amine 1 and p-methoxybenzaldehyde 2. The one-pot reductive amination proceeded by the formation in situ of the N-(5-pyrazolyl)imine 4 as key synthetic intermediate of other valuable pyrazole derivatives. This methodology is distinguished by its operational easiness, short reaction time, isolation and purification of the aldimine intermediate is not required. The structure of the synthesized N-heterocyclic amine 3 was fully characterized by FTIR-ATR, 1D and 2D NMR experiments, EIMS, and elemental analysis.

In this study, Fe3O4@graphite sheets were successfully synthesized in one-pot via a simple hydrothermal method and subsequently employed as an effective electrocatalyst for hydrogen evolution reaction (HER). HER is the crucial electrochemical reactions for the next-generation energy devices. Hydrogen is a clean and renewable energy resource and is one of the most promising candidates for fuel. The shape of the Fe3O4 nanoparticles is nearly spherical with a size of about 10 nm and the Fe3O4 nanoparticles distributed evenly on the graphite sheets. The synthesized Fe3O4@graphite sheets have a specific surface area about 125 m(2) g(-1) with slit-shaped open micro/mesopores. Overall the physicochemical characterization techniques have confirmed the formation, structural stability, and elemental composition of synthesized Fe3O4@graphite sheets. The resulting Fe3O4@graphite sheets were demonstrated towards electrocatalytic HER in 0.1 M KOH solution. The synthesized Fe3O4@graphite sheets delivered the lowest Tafel slope (78 mV dec(-1)) and overpotential (-120 mV(RHE)) at a current density of 10 mA cm(-2). The electrochemical impedance spectroscopy results demonstrate that HER are highly favorable on the Fe3O4@graphite sheets due to the relatively low charge transfer resistance. The experimental results reveal that Fe3O4@graphite sheets possess remarkable electrocatalytic HER activities and are highly stable. The good electrocatalytic activity of Fe3O4@graphite sheet can be ascribed to the synergistic effect between Fe3O4 and graphite sheets, which can facilitate charge transfer kinetics to enhance electrocatalytic HER performance.

A fast and facile synthesis of TiO2- Al2O3 nanocomposite based on Microwave (MW) irradiation is presented. The nanocomposite development were corroborated by X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), energy-dispersive X-ray (EDX),and Fourier transform infrared spectroscopy (FT-IR)analysis. The XPS analyzed results affirmed that elements on the nanocomposite surface were Al and O. Electrochemical properties of the as prepared TiO2-Al2O3 nanocomposites were studied thoroughly to determine the sensing activity of the nanocomposites towards 3,4-Diaminotoluene (3,4-DAT) which is a harmful or hazardous chemical using I-V method. Selective electrochemical sensor using TiO2-Al2O3 nanocomposite onto glassy carbon electrode (GCE) was assembled and the details electrochemical investigation of 3,4-Diaminotoluene (3,4-DAT) was developed. It was calibrated using in range of 3,4-DAT concentration and data were plotted as current versus concentration. Considering the highest linearity (r(2)=0.99)of calibrated range, the linear dynamic range (1.0 pM similar to 1.0 mu M) was found. Employing the slope of calibration curve, the sensitivity (0.5024×10(3) mu A mu M(-1)cm(-3)) and detection limit (0.19 +/- 0.01 pM) were estimated. Besides this, the selective 3,4-DAT chemical sensor was shown long-term stability and precious reproducibility with very short response time without any interference effect.

Selective hydrogenation of biomass oxygenates to valuable chemicals is a desired catalytic process from energy and environment. Traditional catalysts for selective hydrogenation of biomass oxygenates are prepared from co-impregnation or co-precipitation method. In this work, 93.6% of a 1,4-pentanediol yield as well as high stability was obtained on CeO(2 )supported cobalt and copper species (Cu3Co1/CeO2) by pyrolyzing a MOF composite from one-pot synthesis. Comparison showed that catalytic performances on Cu3Co1/CeO2 were higher than most literature sources, Cu3Co1/CeO2-CP and individual Co-0 or Cu-0 on CeO2. Additionally, Cu3Co1/CeO2 also presents the yields of higher than 92.5% for gamma-valerolactone, furfural, benzaldehyde, acetophenone and phenol to corresponding alcohol products. Characterization results indicated high catalytic results are derived from the coexistence of highly dispersed Cu-0 and strong Lewis acid, copper and cobalt oxides, on Cu3Co1/CeO2 . Redox support CeO2 facilitates dispersion of cobalt while the synergistic effect on dispersion and reduction of cobalt and copper achieves high efficient hydrogenation of biomass oxygenates.

The effect of catalyst restructuring on the polydopamine-supported Pd catalyzed transfer hydrogenation of ethyl 4-nitrobenzoate and the catalytic hydrogenation of (E)-2-methyl-2-butenoic acid is reported. Transmission electron microscopy investigation of different catalyst pre-treatment and reaction conditions revealed high catalytic activity in both reactions unless drastic aggregation of the active metal occurred. In the transfer hydrogenation reaction aggregation was primarily dependent on the H-source used, while in the catalytic hydrogenation additives in combination with the reductive environment led to extensive Pd aggregation and thus decreased catalytic activity. The enantioselective hydrogenation of (E)-2-methyl-2-butenoic acid showed increased enantioselectivity and decreased conversion with increased particle size.

Gallic acid is abundantly found in amla (Phyllanthus emblica), a deciduous of the family phyllanthaceae. Gallic acid, the major constituent of the plant, was methylated to 3,4,5 trimetboxy gallic acid, which then underwent steglich esterification first with paracetamol and then with 4-hydroxy acetophenone to yield 4-acetamidophenyl 3,4,5-trimethoxybenzoate and 4-acetyl phenyl 3,4,5-trimethoxybenzoate respectively. 1H NMR, 13C NMR, UV, FT-IR and mass spectroscopy were used to characterize the synthesized compounds. Density functional theory (B3YLP) using a 6-31G (d,p) basis set has been used for quantum chemical calculations. AIM (Atom in a molecule) approach depicted weak molecular interactions within the molecules, whereas the reactive site and reactivity within the molecule were examined by global and local reactivity descriptors. The HOMO and LUMO energies and frontier orbital energy gaps were calculated by time dependent DFT approach using the IEFPCM model. A small value for the HOMO-LUMO energy gap indicated that easier charge transfer occurs within compound 4. The nucleophilic and electrophilic reactivity was determined by MEP (molecular electrostatic potential) experiment. Polarizability, dipole moment, and first hyperpolarizability values were calculated to depict the NLO (nonlinear optical) property of both the synthesized compounds. The antimicrobial activity was also carried out and broad-spectrum antibacterial activity against several strains of bacteria and certain unicellular fungi were exhibited by synthesized compound 3.

Targeting Streptococcus mutans is the primary focus in reducing dental caries, one of the most common maladies in the world. Previously, our groups discovered a potent bactericidal biaryl compound that was inspired by the natural product honokiol. Herein, a structure activity relationship (SAR) study to ascertain structural motifs key to inhibition is outlined. Furthermore, mechanism studies show that bacterial membrane disruption is central to the bacterial growth inhibition. During this process, it was discovered that analog C2 demonstrated a 4-fold better therapeutic index compared to the commercially available antimicrobial cetylpyridinium chloride (CPC) making it a viable alternative for oral care.

A highly inexpensive, and operationally simple seralite SRC-120 (strongly acidic cation exchange resin) catalyzed synthesis of 3,3 ‘-bis(indolyl)methanes (BIMs) from indoles and low/high boiling point carbonyl compounds under solvent-free condition is reported. Synthesis of BIMs with low boiling point carbonyls at room temperature takes prolonged reaction time and give low yields at high temperature. The reported method overcomes these limitations and works remarkably well with low/high boiling point aldehydes/ketones in shorter reaction times (5-10 min) under microwave irradiation conditions and provides moderate to excellent yields (65-94%). Moreover, the recyclability of the catalyst for at least five times without notable loss in activity makes the whole process attractive and green protocol.
