A new nano ‐sized mononuclear Cu (II) complex with N,N‐donor Schiff base ligands: sonochemical synthesis, characterization, molecular modeling and biological activity
A new copper (II) Schiff base complex has been synthesized by reflux and sonochemical methods and was confirmed by different spectroscopic techniques. The complexes (bulk and nano) have been screened for their in vitro microbiology activity against four types of bacteria and three strains of fungi. Finally, the copper complex was optimized at the DFT ‐B3LYP/6–31 + G(d) calculation level using the Gaussian 03 package. A new, simple Cu2+ nano ‐structure Schiff base complex in methanol medium has been synthesized by the ultrasonic method. Structure of the compound was confirmed by FT‐IR, GC‐Mass and other spectros...

Synthesis, characterization and catalytic performance of core ‐shell structure magnetic Fe3O4/P(GMA‐EGDMA)‐NH2/HPG‐COOH‐Pd catalyst
Fe3O4/P(GMA ‐EGDMA)‐NH2/HPG ‐COOH‐Pd microspheres are prepared with hyperbranched polymer layer, which can convent 4‐nitrophenol to 4‐aminophenol efficiently, and whose catalytic efficiency can still maintain up to 86% after eight cycles catalytic experiments. A strategy has been developed for the synthesis, characterization and catalysis of magnetic Fe3O4/P(GMA ‐EGDMA)‐NH2/HPG ‐COOH‐Pd core‐shell structure supported catalyst. The P(GMA‐EGDMA) polymer layer was coated on the surface of hollow magnetic Fe3O4 microspheres through the effect of KH570. The core ‐shell magnetic Fe3O4/P(GMA ‐EGDMA) mo...

Influence of imide functionalized organo ‐modified Mg‐Al layered double hydroxide on the thermal and mechanical properties of new aliphatic‐aromatic poly (amide‐imide)
Two new series nanocomposites were prepared from a new synthesized poly(amideimide) and two organo modified LDH. The effects of organic modifier structure on the thermal and mechanical properties of resulted poly(amide ‐imide)/Mg‐Al LDH nanocomposites were investigated. A new dicarboxylic acid modified Mg ‐Al LDH (DLDH) containing imide groups was prepared and its effects on the thermal and mechanical properties of the new synthesized aliphatic‐aromatic poly (amide‐imide) (PAI) were investigated via preparation of PAI/nanocomposite films by solution casting method. The results of X‐ray diffra ction (XRD), field...

A cost ‐effective shortcut to prepare organoselenium catalysts via decarboxylative coupling of phenylacetic acid with elemental selenium
Decarboxylative coupling of phenylacetic acid with elemental selenium led to a cost ‐effective shortcut to prepare organoselenium catalyst. An interesting decarboxylative coupling reaction of phenylacetic acid with elemental selenium was discovered and employed for the preparation efficient organoselenium catalysts for Baeyer –Villiger reaction and oxidative deoximation reaction. Compared with the traditionally used Grignard reagent method, the decarboxylative coupling reaction with selenium powders provides a shortcut for the preparation of organoselenium catalysts free of carcinogenic organohalide starting materials,...

Synergistic Activities in the Ullmann Coupling of Chloroarenes at Ambient Temperature by Pd ‐Supported Calcined Ferrocenated La2O3
Ullmann coupling of chloroarenes catalyzed by Pd ‐supported calcined ferrocenated La2O3 at ambient conditions.
Two main active sites that drive the reaction in a synergistic fashion.
A coupling of acetyl and aryl moieties as a by ‐product. Novel palladium ‐doped nanoparticles have been explored to serve as the first metal oxide‐derived heterogeneous catalyst for Ullmann reaction of chloroarenes under mild condition (34 °C). This heterogeneous catalyst exhibited high catalytic activity towards the Ullmann homocoupling of chloroarenes into a seri es of useful symmetrically biaryl products with good to excellent yie...

Quinoline and ferrocene conjugates: Synthesis, computational study and biological evaluations
O ‐ and N‐regioisomers of new quinoline‐ferrocene conjugates exhibit different cytostatic activity. NovelO‐alkylated quinoline andN‐alkylated 4‐quinolone derivatives attached to the ferrocene moiety through 4,1‐ (7a –d,8a –d and12a –d) and 1,4 ‐disubstituted (9a,9b,10a and10b) 1,2,3 ‐triazole moiety were synthesized. The observed regioselectivity ofO‐ vs.N‐alkylation was explored by the use of NMR and computational techniques. Among theN‐alkylated derivatives, the quinolone‐ferrocene conjugate9a displayed marked activities against chronic myeloid leukemia in blast crisis (K562) and Burkitt l...
