Pedersen, Samuel K. published the artcileMain element chemistry enables gas-cylinder-free hydroformylations, Application In Synthesis of 1205-17-0, the main research area is alkene syngas hydroformylation main element chem.

Industrially, aldehydes are produced annually on a multimillion-tonne scale via the hydroformylation of olefins with syngas (CO/H2 mixture). Nonetheless, this transformation has not found frequent use in the laboratory Here, a simple strategy for the concerted generation of syngas from two accessible and crystalline main element compounds with just water as the primary activator for syngas release is reported. By decoupling the syngas formation and consumption via a two-chamber reactor, this low-pressure, low-temperature and near-stoichiometric hydroformylation operates efficiently on a diverse array of terminal olefins without the need for expensive equipment. This approach provides unique opportunities to access aldehydes in a safe and reliable manner with further adaptation to the synthesis of a range of pharmaceuticals and relevant mols. thereof. This strategy is adaptable to carbon isotope labeling as demonstrated by the use of a 13CO releasing mol. It’s anticipated that this hydroformylation approach will provide a complementary toolbox for drug discovery and development.

Shirase, Satoru published the artcileCerium(IV) Carboxylate Photocatalyst for Catalytic Radical Formation from Carboxylic Acids: Decarboxylative Oxygenation of Aliphatic Carboxylic Acids and Lactonization of Aromatic Carboxylic Acids, Name: 4-Methoxyphenylacetic acid, the main research area is aldehyde alc preparation; carboxylic acid decarboxylative oxygenation cerium carboxylate photocatalyst.

We found that in situ generated cerium(IV) carboxylate generated by mixing the precursor Ce(OtBu)4 with the corresponding carboxylic acids served as efficient photocatalysts for the direct formation of carboxyl radicals from carboxylic acids under blue light-emitting diodes (blue LEDs) irradiation and air, resulting in catalytic decarboxylative oxygenation of aliphatic carboxylic acids to give C-O bond-forming products such as aldehydes and ketones. Control experiments revealed that hexanuclear Ce(IV) carboxylate clusters initially formed in the reaction mixture and the ligand-to-metal charge transfer nature of the Ce(IV) carboxylate clusters was responsible for the high catalytic performance to transform the carboxylate ligands to the carboxyl radical. In addition, the Ce(IV) carboxylate cluster catalyzed direct lactonization of 2-isopropylbenzoic acid to produce the corresponding peroxy lactone and γ-lactone via intramol. 1,5-hydrogen atom transfer (1,5-HAT).

Scrivanti, Alberto published the artcileArylation of β-methallyl alcohol catalyzed by Pd(OAc)2 in combination with P(t-Bu)3: application to fragrance synthesis, Recommanded Product: 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde, the main research area is arylmethylpropana helional canthoxal lilial preparation fragrance; methallyl alc arylation aryl bromide catalyst palladium phosphine.

Pd(OAc)2 in combination with P(t-Bu)3 catalyzes the coupling of β-methallyl alc. with 1-bromo-3,4-(methylenedioxy)benzene (I), 1-bromo-4-methoxybenzene (II), or 1-bromo-4-tert-butylbenzene (III). The reaction affords the corresponding 2-methyl-3-aryl-propanals, which are valuable floral fragrances. With I or II high reaction rates are obtained at 130 °C using NMP/water mixtures and an inorganic base such as Na2CO3. The chemoselectivity of the reaction is almost complete, so that the process appears practically feasible. In contrast, the coupling of β-methallyl alc. with III proceeds with low reaction rates.

Ud Din, Zia published the artcileOptimized one-pot synthesis of monoarylidene and unsymmetrical diarylidene cycloalkanones, Computed Properties of 86-51-1, the main research area is monoarylidene diarylidene cycloalkanone preparation green chem; ketone condensation aryl aldehyde dimethylammonium dimethylcarbamate catalyst.

Ionic liquid dimethylammonium dimethylcarbamate (DIMCARB) catalyzed reaction for the synthesis of monoarylidene cycloalkanones I (X = nothing, CH2, O; R1 = Ph, 2-MeC6H4, 4-MeOC6H4, 1,3-benzodioxol-5-yl, etc.) and unsym. diarylidene cyclohexanones II (R2 = Ph, 4-ClC6H4, 4-BrC6H4, 4-O2NC6H4, 4-FC6H4, 4-Me2NC6H4) has been developed. Both cyclic and acyclic ketones were reacted with a variety of electron-donating and withdrawing-substituted aldehydes in the presence of a catalytic amount of DIMCARB in a green solvent (aqueous ethanol) providing the corresponding monoarylidene ketones, e.g. I, in low to excellent yields. Subsequent condensation of 2-(4-methoxybenzylidene)cyclohexanone with various aromatic aldehydes under basic conditions allowed for the preparation of unsym. diarylidene cyclohexanones II. This synthetic methodol. provides mild, efficient, and environmentally friendly access to unsym. curcuminoid analogs, avoiding the use of excess catalysts, chlorinated organic solvent, and high temperature reaction. It is green and environmentally sound alternative to the existing protocols for the synthesis of pharmaceutically important unsym. natural product analogs.

The bis-coumarin analogs I (Ar = Ph, 5-nitrothiophen-2-yl, 6-methylpyridin-2-yl, etc.) were synthesized in high yield using the reaction of 1 equiv of aryl aldehydes ArCHO with 2 equiv of 4-hydroxycoumarin in water under microwave irradiation conditions. SEM, transmission electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, thermogravimetric anal., dynamic light scattering, vibrating sample magnetometry, Fourier transform IR spectroscopy, UV-visible absorption, and Brunauer-Emmett-Teller techniques confirmed the successful synthesis of the catalyst. The main attractive characteristics of the presented green protocol are very short reaction times (10-15 min), excellent yields, and the avoidance of hazardous or toxic reagent and solvents. Thermal durability, easy separation, and high reusability are important advantages of the new catalyst in comparison to other catalysts.
