Fe3O4 magnetic nanoparticles were synthesized by co-precipitation of Fe2+ and Fe3+ in aqueous NaOH. Then silica was coated on the obtained nanoparticles and the whole composite was functionalized with chlorosulfonic acid in CH2Cl2. The obtained nanocomposite (Fe3O4@SiO2-SO3H) was characterized by FT-IR, VSM and XRD techniques and was used as an efficient catalyst in condensation reaction of ind...

In an experiment, 200 one-day-old broiler chickens (Ross 308) were used to investigate the effects of sumac fruit (Rhus coriaria L.) powder (SFP) on performance, plasma concentrations of total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL-c), low density lipoprotein (LDL-c), very low density lipoprotein (VLDL-c) and plasma fasting blood sugar (FBS), as well as proportional ...

The title compound, C(18)H(17)NO(4), was obtained accidentally through acid-catalysed aromatization of a phthalimide-substituted 2-(1-hy-droxy-eth-yl)cyclo-hex-2-enone. It exhibits an intra-molecular O-H⋯O(c) (c = carbonyl) hydrogen bond and forms a three-dimensional network structure via π-π stacking inter-actions between adjacent benzene rings (phthalimide-to-phenyl-ene and phthalimide-to-pht...

Novel multi-SO3H functionalized strong Brønsted acidic ionic liquid coated magnetite nanoparticles have been prepared and applied as catalyst for the synthesis of 2,4,5-trisubstituted imidazoles. The results showed that a novel catalyst was very efficient for the reaction and could be magnetically separated and reused at least 6 times with less reduction in its catalytic activity. Operational s...

Four new macrocyclic-phthalimide ligands were synthesised via the coupling of N-(3-bromopropyl)phthalimide either to cyclen (1,4,7,10-tetraazacyclododecane) itself or its carboxylate-functionalized analogues, and photophysical studies were carried out on their corresponding Tb(III) complexes in aqueous media as a function of pH. Luminescence intensities of Tb·L1a–Tb·L3a were in ‘switched off’ m...

During an attempt to prepare a cocrystal of N-phenyl-phthalimide, C(14)H(9)NO(2), with N-(2,3,4,5,6-penta-fluoro-phen-yl)phthalimide, a new ortho-rhom-bic polymorph of the first component was obtained. This new form has Z' = 0.5 and the mol-ecule is located around a twofold axis, whereas in the previously reported polymorph (space group Pbca), the mol-ecule has no crystallographically imposed s...

a facile one step synthesis of anilino alky1-n-substituted phthalimide i is reported. the following compounds belonging to this series were made: 1. (anilino-n-ethyl) phthalimide 8 2. (3,4, 5-trimethoxy anilino-n-ethyl) phthalimide 6 3. (3,4, 5-trimethoxy anilino-n-propyl) phthalimide 7 4. n-(ethyl phthalirnido-p-amino benzoyl) glutamic acid diethyl ester 10 5. n-(propyl phthalimido-p-amino ben...

Detailed crystal structures and H-NMR characteristics of some alkylaminephthalimides, including dendritic polyphthalimides, are reported. These investigations were undertaken in order to obtain a better understanding of the relationship between solid-state supramolecular interactions, their persistence in solution and associated dynamics of magnetically hypersensitive phthalimide aromatic AA’BB...

sulfonic acid functionalized sba-15 (sba-pr-so3h) with pore size 6 nm as an efficient heterogeneous nanoporous solid acid catalyst exhibited good catalytic activity in the biginelli-like reaction in the synthesis of spiroheterobicyclic rings with good yield and good recyclability. spiro-pyrimidinethiones/spiro-pyrimidinones-barbituric acid derivatives were synthesized in a simple and efficient ...
