Shen, Tao published the artcileEfficient, solvent-free aminolysis of monoesters catalyzed by sodium, Category: esters-buliding-blocks, the main research area is ester sodium catalyst aminolysis; amide preparation.

An efficient, solvent-free procedure using sodium as catalyst for the aminolysis of monoesters was reported. A detailed comparison of catalysts between sodium and sodium amide was made. It was found that the fresh sodium amide by in-situ synthesis of sodium with ammonia was more active than the indirectly adding sodium amide. As compared to the previously reported approaches, the procedure given in this work was much faster and performed under mild conditions. Furthermore, this procedure was applied successfully for the aminolysis of other monoesters.

Gaaffar, I. F. published the artcileComparison of identified compounds from extracted Pelargonium Radula leaves by supercritical fluid extraction and commercial geranium essential oil, COA of Formula: C9H10O2, the main research area is geranium essential oil supercritical fluid extraction Pelargonium Radula leave.

Supercritical fluid extraction (SFE) is a green technol. that is convenient to extract Pelargonium radula (P. radula) leaves without leaving any neg. impacts on the environment. It is an alternative approach to reduce the solvent residual problem during the extraction process. Therefore, this research was performed to compare the active ingredients extracted by SFE technique with the commercialized geranium essential oil in the market. Extraction of powd. P. radula leaves by supercritical carbon dioxide (SC-CO2) was operated at constant pressure, temperature, and solvent flowrate which were 100 bar, 40°C, and 24 mL/min, resp. SC-CO2 extraction on P. radula leaves result in 0.19% of oil yield. By comparing extracted P. radula oil with the commercialized geranium essential oil, both oil consists of benzyl acetate, citronellol, geraniol, e-amyl cinnamaldehyde, iso-Pr tetradecanoate, and iso-Pr hexadecanoate.

Feng, Xuanyu published the artcileAluminum Hydroxide Secondary Building Units in a Metal-Organic Framework Support Earth-Abundant Metal Catalysts for Broad-Scope Organic Transformations, Application In Synthesis of 140-11-4, the main research area is metal organic framework catalyst organic transformation.

The intrinsic heterogeneity of alumina (Al2O3) surface presents a challenge for the development of alumina-supported single-site heterogeneous catalysts and hinders the characterization of catalytic species at the mol. level as well as the elucidation of mechanistic details of the catalytic reactions. Here we report the use of aluminum hydroxide secondary building units (SBUs) in the MIL-53(Al) metal-organic framework (MOF) with the formula Al(μ2-OH)(BDC) (BDC = 1,4-benzenedicarboxylate) as a uniform and structurally defined functional mimic of Al2O3 surface for supporting Earth-abundant metal (EAM) catalysts. The μ2-OH groups in MIL-53(Al) SBUs were readily deprotonated and metalated with CoCl2 and FeCl2 to afford MIL-53(Al)-CoCl and MIL-53(Al)-FeCl precatalysts which were characterized by powder X-ray diffraction, nitrogen sorption, elemental anal., d. functional theory, and extended X-ray fine structure spectroscopy. Activation with NaBEt3H converted MIL-53(Al)-CoCl to MIL-53(Al)-CoH which effectively catalyzed hydroboration of alkynes and nitriles and hydrosilylation of esters. XPS and X-ray absorption near-edge spectroscopy (XANES) indicated the presence of AlIII and CoII centers in MIL-53(Al)-CoH while deuterium labeling studies suggested σ-bond metathesis as a key step for the MIL-53(Al)-CoH-catalyzed addition reactions. MIL-53(Al)-FeCl competently catalyzed oxidative Csp3-H amination and Wacker-type alkene oxidation XANES anal. revealed the oxidation of FeII to FeIII centers in the activated MIL-53(Al)-FeCl catalyst and suggested that oxidative Csp3-H amination occurs via the formation of FeIII-OtBu species by single electron transfer between FeII centers in MIL-53(Al)-FeCl and (tBuO)2 with concomitant generation of 1 equiv of tBuO· radical, C-H activation through hydrogen atom abstraction to generate alkyl radicals, protonation of FeIII-OtBu by aniline to generate MIL-53(Al)-FeIII-anilide, and finally C-N coupling between the FeIII-anilide and alkyl radical to form the Csp3-H amination product and regenerate the FeII catalyst. These highly active single-site MOF-based solid catalysts were readily recovered and reused up to five times without significant decrease in catalytic activity. This work thus demonstrates the great potential of using the aluminum hydroxide SBUs in MOFs to support EAM catalysts for important organic transformations.

Three dinuclear dysprosium complexes, [Dy2(hmb)2(OTf)2(H2O)4].HOTf.2THF (A.HOTf.2THF), [Dy2(hmb)2(OTf)2(H2O)4].(CH3)2CO (A.(CH3)2CO) and [Dy2(hmi)3(H2O)2].2HOTf (B.2HOTf), were synthesized by the reaction of Dy(OTf)3 and the Schiff-base ligands H2hmb (N’-(2-hydroxy-3-methoxybenzylidene)benzohydrazide) or H2hmi ((2-hydroxy-3-methoxyphenyl)methylene isonicotinohydrazine). Complex A.HOTf.2THF was an effective and chemoselective catalyst for the deacetylation of esters in methanol. This method offered an efficient route to selectively deacetylated monosaccharides and disaccharides in high yields and a green catalyst that can be easily recycled and reused. This method was especially valuable for the preparation of peracetylated hemiacetal of monosaccharides and disaccharides with yields of 85 to 88 and 65 to 85%, resp. Complex (B.2HOTf), in comparison, indicated that coordinated triflate ions were key to activation of the regioselective anomeric deacetylation.

Zhang, Yihan published the artcileZinc-triggered photocatalytic selective synthesis of benzyl acetate on inverse spinel CuFe2O4 3D networks: a case of coupled redox photocatalytic reaction, Category: esters-buliding-blocks, the main research area is benzyl acetate preparation DFT; benzaldehyde zinc triggered copper iron oxide photocatalyst coupled redox.

Herein, a Zn-doped CuFe2O4 3D network for the coupled redox photocatalytic (CRP) reaction to generate benzyl acetates I [R = Ph, 4-MeC6H4, 4-ClC6H4, etc.] with high selectivity was developed. The ammonia assisted sol-gel method helped to improve the sp. surface area of inverse spinel CuFe2O4 and therefore the concentration of oxygen vacancies. With an optimized doping content of 0.5%, Zn-doped CuFe2O4 presented a photocurrent as high as 34.72μA cm-2, which indicated that Zn-doping largely boosted the charge separation efficiency in accordance with the surface photovoltage measurement. Most importantly, in the CRP reaction, zinc triggered the selectivity of benzaldehyde to benzyl acetate from 2.97% to 74.80%. D. functional theory (DFT) calculations further revealed that zinc doping enhanced the adsorption energy of the intermediate product of acetone in CuFe2O4-based CRP reaction leading to enhanced activity and selectivity.

Bazyar, Zahra published the artcileOn/Off O2 Switchable Photocatalytic Oxidative and Protodecarboxylation of Carboxylic Acids, Product Details of C9H10O2, the main research area is photocatalytic oxidative protodecarboxylation carboxylic acid.

Photoredox catalysis in recent years has manifested a powerful branch of science in organic synthesis. Although merging photoredox and metal catalysts has been a widely used method, switchable heterogeneous photoredox catalysis has rarely been considered. Herein, we open a new window to use a switchable heterogeneous photoredox catalyst which could be turned on/off by changing a simple stimulus (O2) for two opponent reactions, namely, oxidative and protodecarboxylation. Using this strategy, we demonstrate that Au@ZnO core-shell nanoparticles could be used as a switchable photocatalyst which has good catalytic activity to absorb visible light due to the localized surface plasmon resonance effect of gold, can decarboxylate a wide range of aromatic and aliphatic carboxylic acids, have multiple reusability, and are a reasonable candidate for synthesizing both aldehydes/ketones and alkane/arenes in a large-scale set up. Some biol. active mols. are also shown via examples of the direct oxidative and protodecarboxylation which widely provided pharmaceutical agents.
