“…Hydrogen peroxide is a cheap and green oxidant for oxidation of a large number of substrates. [11] Literature survey shows that oxidation of 1,4-dihydropyridine derivatives using H 2 O 2 in the presence of urea, [12,13] acetic acid, [14] AlCl 3, [15] NaI, [16] SiO 2 -VO (OH) 2, [17] MoO 3, [18] KBr/HOAc [19] as a catalyst, has been reported. In addition, metal-organic frameworks (MOFs) as heterogeneous catalysts have been successfully applied as catalysts in oxidation and hydrogenation reactions.…”

A facile and efficient method was described for oxidation of some 3,5-diacyl or 3,5-diester 1,4-dihydropyridines using H 2 O 2 in the presence of superparamagnetic core-shell metal-organic framework Fe 3 O 4 @Ni-MOF. The Fe 3 O 4 @Ni-MOF has been obtained byStep-by-Step method in which magnetic Fe 3 O 4 magnetic nanoparticles were coated with Ni-MOF using a mercaptoacetic acid linker. The synthesized catalyst was characterized using thermogravimetric analysis, FT-IR spectroscopy, powder X-ray diffraction, field emission scanning electron microscopy and energy-dispersive X-ray analysis. The novel superparamagnetic core-shell metal-organic framework Fe 3 O 4 @Ni-MOF revealed high efficiency for oxidation of various 1,4-dihydropyridines using hydrogen peroxide. The Box-Behnken design matrix and the response surface method were applied to investigate the optimization of the reaction conditions. The conditions for optimal reaction yield and time were: amount of catalyst ≈17 mmol, temperature ≈78 C and amount of hydrogen peroxide ≈ 1 ml. A variety of 3,5-diacyl or 3,5-diester 1,4-dihydropyridines with different substituted functional groups have been converted to corresponding pyridines with good to excellent isolated yields using H 2 O 2 and Fe 3 O 4 @Ni-MOF. The catalyst was reused up to five times for the oxidation of 1,4-dihydropyridines without a significant loss in catalytic activity. The short reaction times, simplicity of method, good to excellent yields and reusability of catalyst were some advantages of the proposed procedure.

“…It is fairly clear that most of the particles are approximately spherical in shape and the particle size ranged from 30-47 nm. From the images, it can be confirmed that the particles are smaller in size [57]. To check the chemical composition of the material, an EDX spectroscopy analysis was performed.…”

The present study focused on the fabrication of molybdenum trioxide nanoparticles (MoO3) from a molybdenum complex with N-salicylideneaniline [Mo(C13H10NO)3] ligand as the precursor. The ligand was synthesized and characterized by 1 H NMR and 13 C NMR. The synthesized MoO3 nanoparticles were characterized by powder X-ray diffraction, FT-IR, UV-visible spectroscopy, TG-DTA, SEM-EDX and TEM. The results clearly showed the formation of nanoparticles of MoO3. The absorption spectra of MoO3 at 341 nm revealed the formation of MoO3 by calculating the band gap at 2.8 eV. TG-DTA showed MoO3 was stable up to 800 °C. SEM and TEM analyses clearly indicated the formation of MoO3 nanoparticles in the range of 30-47 nm. The NPs were tested for their cytotoxicity influence on MCF7-human breast adenocarcinoma cell lines. The findings suggested MoO3 had the capacity to kill 50% of viable cells after 24 h of incubation at 37 °C. The observations strongly suggest that MoO3 nanoparticles have therapeutic potential against human breast cancer cells based on the dosage of the drug after an incubation period of 24 h.
