Two novel room-temperature disulfonic acid functionalized ionic liquids derived from 3,5-dimethyl-1H-pyrazole consisting of chloride and trichlorostannate anions, 3,5-dimethyl-1,2-disulfonic acid-1H-pyrazolium chloride and 3,5-dimethyl-1,2-disulfonic acid-1H-pyrazolium trichlorostannate, have been synthesized, characterized and evaluated for their catalytic efficiency in the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones by the one-pot, three-components reaction of phthalhydrazide, an aromatic aldehyde and malononitrile or ethyl cyanoacetate under solvent-free conditions. The results have demonstrated high catalytic activity of these novel ionic liquids containing acidic SO3H groups in producing high yields of the desired products in short reaction time. The ionic liquids can be used at least four times without any noticeable decrease in catalytic activity.

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.

Three novel mixed ligand Zn(II) complexes {complex 1 = [Zn(L1)(2)(bpy)], complex 2 = [Zn(L2)(2)(bPY)], complex 3 = [Zn(L2)(2)(phen)], where bpy = 2,2′-bipyridine and phen = 1,10-phenanthroline} of 4-(4-chlorobenzoyl)-2-(3-chlorophenyl)-5-methyl-2,4-dihydro-3H-pyrazol-3-one (HL1) and 4-(4-chlorobenzoyl)-5-methyl-2-(p-tolyl)-2,4-dihydro-3H-pyrazol-3-one (HL2) were synthesized and characterized by H-1 and C-13 NMR, FTIR, TG-DTA, UV-Vis, elemental analysis, molar conductance and single crystal X-ray structure determination. Based on analytical and spectroscopic techniques, all the three Zn(II) complexes were found to have a distorted octahedral geometry. The ligands and the complexes were screened for antimalarial activity against plasmodium falciparum. The zinc(II) complexes showed greater antimalarial activity than their parent ligands.

A palladium-catalyzed oxidative dehydrogenation reaction in the presence of AMS and base to synthesize pyrazolones and pyrazoles was identified. This method can be utilized to a wide range of substrates, operates under mild react conditions and can give high yields. We believe it could be used as an alternative protocol for the classical dehydrogenation reactions. (C) 2019 Published by Elsevier Ltd.

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.

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. SDS of cas: 83-10-3.

A series of new 9,9-diethylfluorenes consisting of three side-arms each bearing a heterocyclic, bis(carboxymethyl)amino, bis(carbamoylmethyl)amino, bis(ethoxycarbonylmethyl)amino or an amino group were prepared on the basis of 2,4,7-tris(bromomethyl)-9,9-diethylfluorene. Imidazolyl, benzimidazolyl, pyrazolyl, pyrrolyl, 1,3-dioxoisoindolyl and pyridinium groups were taken into account as heterocyclic units, attached to the aromatic skeleton via -CH2-, -CH2NHCH2- or -CH2N=CH- linkers. In addition to the seventeen 2,4,7-trisubstituted 9,9-diethylfluorenes, two macrocyclic compounds were prepared on the basis of 2,7-bis(aminomethyl)-9,9-diethylfluorene. The excellent yield of the macrocyclization reaction is worth a special mention. Both the acyclic and the macrocyclic fluorene-based compounds have, among other things, the potential to act as artificial receptors for different substrates in analogy to the known receptors consisting of a benzene or biphenyl core.

Based on the agrochemical structure of anthranilic diamides, fourteen novel N-substittitedphenyl-2-pyrazolylnicotinamides were conveniently synthesized with 2-chloro-3-cyanopyridine and 4-bromopyrazole or 3,5-dimethylpyrazole as starting materials, via an acyl transposing design strategy. Their structures were characterized by 1H NMR, 13C NMR and HRMS. The preliminary bioassay tests indicated that most of these compounds exhibited obvious insecticidal activity at the test concentration of 200 mg/L, among which N-(4-chloro-2-(ethylcarbamoyl)-6-methylphenyl)-2-(3,5-dimethyl-1H-pyrazol-1-yl)nicotinamide (II) possessed a 70% mortality rate against Mythimna separata Walker: some of the compounds displayed favorable fungicidal activities at 50 mg/L towards Physalospora piricola and Alternaria solani Sorauer, especially 2-(4-bromo-1H-pyrazol-1-yl)-N-(2-(cyclopropylcarbamoyl)-4-iodo-6-methylphenyl)nicotinamide (If) and 2-(4-bromo-1H-pyrazol-1-yl)-N-(4-chloro-2-(ethylcarbamoyl)-6-methylphenyl)nicotinamide (Ih) against Physalospora piricola, and 2-(4-bromo-1H-pyrazol-1-yl)-N-(4-chloro-2-(propylcarbamoyl)phenyl)nicotinamide (Id) against Alternaria solani Sorauer had growth inhibitory rates of 62.9%, 54.3% and 54.5%, respectively.
