CO2 capture by ionic liquids has been successfully achieved, indicating that the adsorption of CO2 plays an important role in the activation and transformation of CO2. In this work, highly efficient capture of CO2 is investigated with several novel ILs, which were prepared from bicyclic amidine (DBN) with pyrazole derivatives. Among the kinds of DBN-based ILs, it is found that the optimal absorption capacity (0.93 mol CO2/mol IL) can be achieved by [DBNH][3-MethylPyr] at 40 degrees C and atmospheric pressure. In view of analysis, the significant increase in CO2 capacity was affected by the reactivity of activated nitrogen, steric hindrance and the type of substituents. On the basis of the spectroscopic investigation and Density Functional Theory (DFT) calculation, the absorption mechanism was illustrated, it was verified that anions can react with CO2 to form carbamates. Meanwhile, charge analysis reasonably elucidated the diversity of absorption capacity in various ILs. It suggested that electric-charge distribution of activated nitrogen in pyrazole ring system can play an important role in determining the reaction of ILs with CO2. Consequently, DBN-based ILs can be excellent candidates for CO2 capture. (C) 2020 Elsevier B.V. All rights reserved.

An enantioselective Mannich reaction between 3-fluorooxindoles and pyrazolinone ketimines has been developed for the construction of amino-pyrazolone-oxindoles containing stereogenic C-F units. Based on this new protocol that allows for the generation of two adjacent tetrasubstituted stereocenters, a variety of structurally diverse fluorinated amino-pyrazolone-oxindoles were obtained in good to excellent yields with excellent diastereoselectivities and enantioselectivities (up to 98% yield, >20 : 1 dr and >99% ee). What’s more, good yield and high stereoselectivities were obtained in the gram-scale reaction.

Formula: C5H8N2

The reaction of sym-bis(P-chlorodiphenyl)-carbodiphosphorane (1) with difunctional nucleophiles leads to carbodiphosphoranes carrying two additional chelating N-donor functionalities. A proof of concept is demonstrated by the synthesis and characterization of sym-bis(3,5-dimethyl-1H-pyrazol-1-yl)-carbodiphosphorane (CDP((3,5-Me)Pz)(2), 2) and sym-bis(pyridin-2-yloxy)carbodiphosphorane (CDP(O-Py-2)(2), 3). Due to their superbasic central two-/four-electron carbon donor functionality, these neutral ligands are electronically flexible to act as neutral six-or eight-electron donors, as pincer ligand templates, or as two geminally metal bridging ligands. Their potential to form monoand dinuclear complexes involving two 6-ring or two 5-ring N,C-chelate ring motives has been explored. Complexes of 2 and 3 with fac-[M(CO)(3)] fragments (ls d(6); M = Cr, Mo, W) were used as spectroscopic probes. They reveal a strong sigma-donor and potential pi-donor ability of the central carbon donor pushing electron density for enhanced M-CO back-bonding into the metal d orbitals. DFT calculations consolidate this observation. Dinuclear and multinuclear d(10) Cu(I) complexes have been formed and structurally investigated upon treating these CDP ligands 2 and 3 with CuX (X = Cl, Br, I).

Background: The Islamic Republic of Iran is at high risk of natural disasters. Households are the basic unit of society and they need to be prepared for disasters. Aims: This study assessed disaster preparedness among Iranian households in 2015. Methods: Using multistage cluster sampling, 2968 households in the catchment area of 53 public health departments in all 30 provinces of the Islamic Republic of Iran were surveyed on the disaster preparedness measures they had taken in the past year. The data collection questionnaire included 15 disaster preparedness measures. The mean preparedness score was calculated and its association with residence (urban versus rural), house ownership (owner versus renter) and education level of the head of the household (illiterate, elementary school, middle school, high school, university) was evaluated. Results: The mean score for household disaster preparedness was 9.3 out of 100 (95% confidence interval: 8.3-10.3). Multivariate analysis showed higher preparedness among rural than urban households (P = 0.02). Higher education level was positively associated with a higher preparedness score (P < 0.001), as was house ownership (P < 0.001). Conclusion: The level of household disaster preparedness in the Islamic Republic of Iran in 2015 was low. In line with the first priority for action of the Sendai Framework for Disaster Risk Reduction, the current study provides an overall picture of household disaster preparedness in the Islamic Republic of Iran. This estimation can be used as a baseline value for policy-making, planning, and evaluation of public awareness of disasters in the country. Computed Properties of C12H12N2O3.

The changes in spectra and intensities of the streamwise component of turbulent velocity are calculated in the inflow of a turbine rotor. The flow is initially calculated in the limit when the turbulence is of small scale compared with the rotor diameter. Rapid distortion theory (RDT), Batchelor & Proudman (Q. J. Mech. Appl. Maths, vol. 7 (1), 1954, pp. 83-103) (BP), for small-scale turbulence is combined with the effect of the fluctuating potential flow field on the turbulence caused by the direct interaction of the incident turbulence with the rotor as a sheet of resistance. A second computation is then carried out for turbulence of larger length scale. The results of the calculations are compared with velocity measurements in the inflow of both a commercial wind turbine and a tidal turbine rotor.

An efficient Zn(OTf)(2)-catalyzed regioselective C-N bond making reaction between a bunch of aryl/heteroaryl-substituted para-quinone methides as ideal 1,6-acceptors and various aromatic/non-aromatic aza-heterocycles bearing N-H moiety namely carbazoles, pyrazoles, indazole, benzotriazole and saccharin is reported. This 1,6-aza-Michael technique delivers predominantly NI-diarylmethyl-substituted heterocyclic scaffolds bearing a valuable phenolic moiety in good to high yields with an excellent regioselectivity. Furthermore, this LUMO lowering catalytic system allows different kinds of useful functionalities and excels with broad substrates under mild conditions. Importantly, our control experiments suggested that N2-adducts of indazole, benzotriazole and 3-methyl pyrazole as minor isomers were progressively converted into N1-adducts during the reaction via a retro-aza-Michael reaction triggered by Zn(OTf)(2), offering excellent regioselectivities of the products.
