Zhao, Peng; El-kott, Attalla; Ahmed, Ahmed Ezzat; Khames, Ahmed; Zein, Mohamed Abdellatif published the artcile< Green synthesis of gold nanoparticles (Au NPs) using Tribulus terrestris extract: Investigation of its catalytic activity in the oxidation of sulfides to sulfoxides and study of its anti-acute leukemia activity>, Computed Properties of 699-12-7, the main research area is green preparation gold nanoparticle; XRD particle size distribution gold nanoparticle; sulfide oxidation gold nanoparticle catalyst; sulfoxide preparation catalyst gold nanoparticle; antiacute leukemia activity gold nanoparticle; antioxidant activity gold nanoparticle; cytotoxicity gold nanoparticle.

With regards to applied, facile, green chem. research, a bio-inspired approach is being reported for the synthesis of Au NPs by using Tribulus terrestris extract The innate oxygenated phytochems. facilitated the green reduction of Au3+ ions to corresponding NPs and also stabilized them by encapsulating them. This modification prevented the as-synthesized Au NPs towards agglomeration and tiny NPs were obtained in uniformly spherical in shape and at 10-15 nm dimension. Physicochem. characteristics of the green synthesized Au NPs were evaluated by advanced physicochem. techniques like UV-visible and FTIR spectroscopy, SEM, TEM, EDX and XRD study. Catalytic performance of the biomol. functionalized Au NPs was studied in the controlled and selective oxidation of sulfides to sulfoxides using hydrogen peroxide as green oxidant at room temperature Aromatic, aliphatic and heterocyclic sulfides were oxidized to their corresponding sulfoxides with high yields without formation of over oxidized sulfones. The catalyst was easily recovered and recycled for 8 successive times without noticeable decrease in catalytic activity. In addition, the biosynthesized Au NPs indicated suitable antioxidant and anti-acute leukemia properties against THP-1 cell line. Tribulus terrestris extract and the green synthesized Au NPs exhibited a maximum DPPH scavenging activity of 78% and 29.37%, resp. Again, in the anticancer studies over THP-1 cell line following MTT assay, the Au NP exhibited gradual reduced % cell viability with increase in its concentration At an Au NPs concentration of 2000μg/mL, the % toxicity became maximum suggesting efficient inhibition of cancer invasion. Based on the above results, Au NPs-Tribulus could be administered as a potential anti-leukemia drug for the treatment of acute leukemia following the clin. trial studies in humans.

Li, Hailou; Xu, Xin; Tang, Zhigang; Zhao, Junwei; Chen, Lijuan; Yang, Guo-Yu published the artcile< Three Lanthanide-Functionalized Antimonotungstate Clusters with a {Sb4O4Ln3(H2O)8} Core: Syntheses, Structures, and Properties>, COA of Formula: C8H10OS, the main research area is sodium lanthanide antimonotungstate cluster complex preparation oxidation catalyst; thermal stability luminescence sodium lanthanide antimonotungstate cluster; crystal structure sodium lanthanide antimonotungstate cluster.

Three lanthanide (Ln)-functionalized antimonotungstate (AT) clusters with a {Sb4O4Ln3(H2O)8} core [H2N(CH3)2]14Na8H16[Sb4O4Ln3(H2O)8W2O4(H2O)2(B-α-SbW9O33)4]2·87H2O [Ln = Dy3+ (1), Ho3+ (2), Y3+ (3)] were synthesized in an acidic aqueous solution Their mol. structural unit comprises two {Sb4O4Ln3(H2O)8}-core-incorporated tetrameric [Sb4O4Ln3(H2O)8W2O4(H2O)2 (B-α-SbW9O33)4]19- polyanionic units, each of which is assembled from an unprecedented [Sb4O4Ln3(H2O)8W2O4(H2O)2]17+ heteroatom cluster surrounded by four trivacant [B-α-SbW9O33]9- subunits. What is noteworthy is that a tetrahedral {Sb4O4} cluster is located at the center of the polyanionic unit, as far as we know, which is very infrequent in multi-Ln-functionalized polyoxometalate chem. Solid-state luminescent properties and energy migration of AT ligands to Dy3+ and Ho3+ cations in 1 and 2 have been intensively probed at ambient temperature By varying the exciting wavelength from 250 to 450 nm, the emitting color could vary from blue to yellow for 1 and blue to green-yellow for 2, sep. In addition, high catalytic activities and good reusability of 2 as a heterogeneous catalyst for oxygenation reaction of sulfides have been systematically performed.

Boehmite nanoparticles are aluminum oxide hydroxide (γ-AlOOH) particles, which has large sp. surface area (>120 m2 g-1) and can be prepared using an inexpensive procedure in water. Herein, we present an economical, simple, and environmentally friendly route for the preparation of a copper catalyst on Adenine coated boehmite nanoparticles (Cu-Adenine@boehmite). This catalyst has been characterized by several techniques such as SEM, XRD, AAS, ICP and TGA anal. Cu-Adenine@boehmite was applied as highly efficient and reusable nanocatalyst in carbon-carbon coupling reactions between various aryl halides and sodium tetra-Ph borate, phenylboronic acid, or 3,4-diflorophenylboronic acid under aerobic conditions, palladium-free and phosphine-free ligand. Also this catalyst was applied for the synthesis of polyhydroquinoline derivatives In continuation, selective oxidation of sulfides to sulfoxides using hydrogen peroxide (H2O2) was studied in the presence of Cu-Adenine@boehmite as catalyst. The synthesis of sulfoxides using H2O2 in the presence of Cu-Adenine@boehmite does not generate waste and any byproducts. This catalyst was reused for several times in C-C coupling reaction without loss of its catalytic activity. Reused catalyst was characterized by SEM, XRD and ICP techniques. Heterogeneity and stability of Cu-Adenine@boehmite were studied by hot filtration test, poisoning test and ICP anal.

Makino, Kosho; Tozawa, Kumi; Tanaka, Yuki; Inagaki, Akiko; Tabata, Hidetsugu; Oshitari, Tetsuta; Natsugari, Hideaki; Takahashi, Hideyo published the artcile< Rapid Photoracemization of Chiral Alkyl Aryl Sulfoxides>, Synthetic Route of 699-12-7, the main research area is alkyl aryl sulfoxide photoracemization oxidation potential.

The photoracemization of chiral alkyl aryl sulfoxides with a photosensitizer has not been sufficiently investigated thus far. Therefore, in this study, a rapid photoracemization reaction of enantiopure alkyl aryl sulfoxides using 1 mol % 2,4,6-triphenylpyrylium tetrafluoroborate (TPT+) was developed. Various substitution patterns were tolerated and every racemization reaction proceeded extremely fast (k2 = 1.77 x 104-6.08 x 101 M-1s-1, t1/2 = 0.4-114 s). Some chiral sulfoxides with easily oxidizable functional groups are not appropriate for this photoisomerization. The electrochem. potentials of the functional groups, determined via cyclic voltammetry, are useful for predicting the reactive or nonreactive groups in this photoracemization reaction. A calculation study was conducted to clarify the sp2-like nature of S of the sulfoxide cation radical, which makes photoracemization easier.

Liu, Dongliang; Thomas, Tiju; Gong, Hong; Li, Fei; Li, Qiang; Song, Lijuan; Azhagan, Tamil; Jiang, Heng; Yang, Minghui published the artcile< A mechanism of alkali metal carbonates catalysing the synthesis of β-hydroxyethyl sulfide with mercaptan and ethylene carbonate>, Recommanded Product: 2-(Phenylthio)ethanol, the main research area is alkyl mercaptan dioxolanone potassium carbonate catalyst ring opening hydroxyethylation; hydroxyethyl alkyl sulfide preparation green chem.

A new and green route to synthesize 2-hydroxyethyl n-alkyl sulfide with n-alkyl mercaptan and ethylene carbonate (EC) in the presence of alkali carbonates as catalysts and revealed the mechanism by experiments and theor. calculations The reaction reported proceeded rapidly with high yields when it was performed at 120° C and the catalytic loading is ∼1 mol%. This protocol was applicable to other mercaptans to synthesize the corresponding β-hydroxyethyl sulfide. D. functional theory-based calculations show the energy profile for the reaction pathway. The rate-determining step is the ring-opening of EC. A neg. charged O atom of alkali carbonates approached the S atom of -SH under the influence of hydrogen bonds. An activated S atom that carried more neg. charge serves as a nucleophilic reagent and assists in the ring-opening of EC by reducing the Mayer bond orders of the C1-O1 bond in EC. Alkali cations also contribute to the C1-O1 bond cleavage. The energy barrier for the ring-opening of EC decreases with the decrease of electronegativity of alkali cations. Subsequent transference of a H atom led to the formation of β-hydroxyethyl sulfide, the dissociation of CO2 and the reduction of K2CO3.
