a simple and green synthetic strategy to prepare bao/tio2-zro2 as a solid base catalyst was reported. these materials with various amounts of bao were prepared by the adsorption method. the physical and chemical properties of bao/tio2-zro2 were investigated by x-ray diffraction, x-ray fluorescence, specific surface area and bjh pore size distribution, ft-ir spectroscopy, scanning electron micro...

Six nonlinear, optical chromophores, Z1–Z6, based on the bis(N,N-diethyl)aniline-derived donor and thiolated isophorone bridge, were designed synthesized. The was applied in a chromophore with as an electron bridge for first time. In particular, parts of chromophores Z2–Z6 modified different functional groups, including tert-butyltrimethylsilane tert-butyl(methyl)diphenylsilane derivative: 1,3-...

The title compounds were prepared by reaction of 6-acetyltetralin (1) with different aromatic aldehydes 2a-c, namely 2,6-dichlorobenzaldehyde, 2,6-diflouro-benzaldehyde, and 3-ethoxy-4-hydroxybenzaldehyde, to yield the corresponding a,b-unsaturated ketones 3a-c. Compound 3b was reacted with hydrazine hydrate to yield the corresponding 2-pyrazoline 4, while compounds 3a,b reacted with thiourea t...

Small molecules, namely, DCAO(3)TBDT and DR(3)TBDT, with 2-ethylhexoxy substituted BDT as the central building block and octyl cyanoacetate and 3-ethylrhodanine as different terminal units with the same linkage of dioctyltertthiophene, have been designed and synthesized. The photovoltaic properties of these two molecules as donors and fullerene derivatives as the acceptors in bulk heterojunctio...

A novel series of cyanopyridinyl tetrahydronaphthalene incorporated with different heterocycles were synthesized. The key compounds 2a,b were condensed with chloroacetone and ethyl chloroacetate to give 3a,b and 4a,b, respectively. Also condensation of 4a,b with hydrazine hydrate gave the corresponding hydrazide 5a,b. Reaction of 5b with different isothiocyanates gave the corresponding thiosemi...

This study is dedicated to the comparative investigation of catalytic activity layer-like Faujasite-type (FAU) zeolite X obtained from three different synthesis routes (additive-free route, Li2CO3 and TPOAC route) in a liquid-phase Knoevenagel condensation benzaldehyde ethyl cyanoacetate trans-α-cyanocinnamate. It shown that charge-balancing cations (Na+ K+) morphological properties have strong...

Hydrazonyl bromides 2a,b reacted with active methylene compounds (dibenzoylmethane, acetylacetone, ethyl acetoacetate, phenacyl cyanide, acetoacetanilide, ethyl cyanoacetate, cyanoacetamide and malononitrile) to afford the corresponding 1,3,4,5- tetrasubstituted pyrazole derivatives 5-12a,b. Reaction of 12a,b with formamide, formic acid and triethyl orthoformate give the pyrazolo[3,4-d]pyrimidi...

A series of novel azo-disperse dyes containing alkylhydrazonopyridinone structures were synthesized. 4-Methyl-2,6-dioxo-1-propyl-1,2,5,6-tetrahydropyridine-3-carbonitrile (8) is synthesized by one-pot synthesis using ethyl cyanoacetate, propylamine, and ethyl acetoacetate. Compound 8 is then coupled with aromatic and heteroaromatic diazonium salts to afford the corresponding aryl- and heteroary...

Introduction Malaria is one of the world’s most serious parasitic diseases. There are estimated 300-500 million cases and more than a million deaths from malaria each year. Human malaria is caused by infection with intracellular parasites of the genus Plasmodium that are transmitted by Anopheles mosquitoes. Plasmodium falciparum is the most lethal among the four species of Plasmodium that infec...
