Propylamino-functionalized mesoporous thin films were synthesized via co-condensation of the oxide precursor tetraethoxysilane (TEOS, Merck) and the amine precursor 3-aminopropyltriethoxysilane (APTES, Fluka 98%) in the presence of the template (F127 block copolymer, Aldrich, Mw ~13600). The precursor solution was prepared using 0.8 TEOS:0.2 APTES:0.005 F127:24 EtOH:5.2 H2O:0.28 HCl. This solut...
In the title complex, [InCl(2)(C(24)H(21)N(7))]Cl·C(2)H(5)OH·2H(2)O, the In(III) ion is coordinated by four N atoms from the tris-(benz-imidazol-2-ylmeth-yl)amine (NTB) ligand and two Cl atoms in a distorted octa-hedral environment. In the crystal structure, inter-molecular N-H⋯O, O-H⋯O, O-H⋯Cl and weak C-H⋯Cl hydrogen bonds connect the cations, anions and solvent mol-ecules into a three-dimens...
3-Methyl-1-phenylpyrazol-5-one and its derivatives prepared using ethyl acetoacetate, phenyl hydrazine and its derivatives. Ethyl acetoacetate reacted with phenylhydrazine at reflux temperature to give 3-methyl-1-phenylpyrazol-5-one crude and recrystlized from diluted ethanol to give pure 3-methyl1-phenylpyrazol-5-one. Different pyrazolone derivatives were prepared by using different phenyl hyd...
Oxidation of the facial-type trichloridoruthenium(III) complex bearing ethylbis(2-pyridyl-methyl)amine (ebpma), fac-[Ru(III)Cl3(ebpma)], with an equimolecular amount of (NH4)2[Ce(IV)(NO3)6] in acetonitrile afforded a ligand-based oxidation product of an acetonitriledichloridoruthenium(III) complex having bis(2-pyridylcarbonyl)aminato (bpca), [Ru(III)Cl2(NCCH3)(bpca)]. The complex changed into a...
The title heterocyclic compound, C(20)H(17)NO(3)S, was synthesized by condensation of ethyl cyano-acetate with (Z)-2-benzyl-idenebenzo[b]thio-phen-3(2H)-one in the presence of a basic catalyst in ethanol. The phenyl and ester groups make dihedral angles of 77.67 (6) and 8.52 (6)°, respectively, with the benzothienopyran ring system [maximum r.m.s. deviation = 0.1177 (13) Å]. In the crystal, cen...
Abstract High-surface-area, hexagonal-structured mesoporous silica, MCM-41, was synthesized and wet impregnated with three different amines of 2-(ethylamino) ethanol (EAE), ethylenediamine (EDA), tetraethylenepentamine (TEPA) for use as solid adsorbents in post-combustion CO2 capture application. The adsorption test performed at 25°C atmospheric pressure using 15/85 vol% CO2/N2 a 20-mL/minute f...
In this paper, research will be carried out to classify the blending behavior of glassy and rubbery polymer in solvent with amines. Commercially preface of a polymer prepared from a new monomer is uncertain and enormously expensive. A strategy to introduce new products into the market without a large investment is to take dissimilar polymers, amines and blend them together to make a new product...
Angelmarin (1), a novel anti-cancer agent, was efficiently synthesized through a highly enantioselective epoxidation and a copper cyanide-mediated esterification of the hindered alcohol as the key steps in 53% overall yield.
The title compound, C(14)H(11)ClN(2)O(3)S, with fused thiophene and pyran rings, was synthesized via the condensation of dihydro-thio-phen-3(2H)-one 1,1-dioxide and 2-(3-chloro-benz-yl-idene)malononitrile catalysed by triethyl-amine in ethanol. The thio-phene ring adopts an envelope conformation and the pyran ring is planar (r.m.s. deviation = 0.0067 Å). The dihedral angle between the pyran and...
The unexpected tendency of amines and functionalized hydrazines to reduce ethyl 3-phenylquinoxaline-2-carboxylate 1,4-di-N-oxide (1) to afford a quinoxaline 1c and mono-oxide quinoxalines 1a and 1b is described. The experimental conditions were standardized to the use of two equivalents of amine in ethanol under reflux for two hours,with the aim of studying the distinct reductive profiles of th...
