The new copper(II) complexes [Cu4(pa)4(Bae)4]·H2O (1) and [Cu4(eba)4(Buae)4]·H2O (2) (Hpa = propionic acid, HBae 2-benzylaminoethanol, Heba 2-ethylbutyric acid HBuae 2-butylaminoethanol) were synthesizsed by the interaction of a copper salt with methanol solution respective ligands. single-crystal X-ray diffraction analysis reveals that both compounds have {Cu4(μ3-O)4} cubane-like core. Both sh...

Sir, Body dysmorphic disorder (BDD) is primarily a psychiatric condition, but frequently found in dermatologi-cal settings, where it often goes undetected (1). BDD is characterized by subjective beliefs of physical ugliness or disfigurement despite an objectively normal appearance. Often minor blemishes are blown out of proportion. The affected individual is convinced that others perceive them ...

A novel magnetite nanoparticle-based heterogeneous acidic catalyst [Fe3O4@SiO2@Am-PPC-SO3H] [HSO4] was successfully prepared and characterized by SEM, EDX, TGA, VSM and FT-IR techniques. The magnetically retrievable and sustainable catalyst was investigated in the reaction of aldehyde and o-aminophenol for the synthesis of benzoxazoles. The...

CdO nanoparticles efficiently catalyzes the condensation of aromatic aldehydes with 2-aminophenol at room temperature to afford 2-aryl benzoxazole derivatives by grinding method. The reactions proceed under heterogeneous and mild conditions to provide 2-aryl benzoxazoles in excellent yields (87-97 %) with high purity under solvent free condition. The reaction requires short time (5-23 minutes) ...

The oxidative ring cleavage of aromatic substrates by nonheme Fe dioxygenases is thought to involve formation of a ferrous-(substrate radical) intermediate. Here we describe the synthesis of the trigonal-bipyramdial complex Fe((Ph2)Tp)(ISQ(tBu)) (2), the first synthetic example of an iron(II) center bound to an iminobenzosemiquinonate (ISQ) radical. The unique electronic structure of this S = 3...
