Kim, Junghwa published the artcileIntermolecular Markovnikov-Selective Hydroacylation of Olefins Catalyzed by a Cationic Ruthenium-Hydride Complex, SDS of cas: 1205-17-0, the main research area is branched ketone preparation intermol Markovnikov selective hydroacylation olefin aldehyde; cationic ruthenium hydride complex catalyzed hydroacylation regioselective ketone preparation; aldehyde; alkene; branched ketone; hydroacylation; ruthenium catalyst.

The cationic Ru-H complex was found to be an effective catalyst for the intermol. hydroacylation of aryl-substituted olefins with aldehydes to form branched ketone products. The preliminary kinetic and spectroscopic studies elucidated a ruthenium-acyl complex as the key intermediate species. The catalytic method directly afforded branched ketone products in a highly regioselective manner while tolerating a number of heteroatom functional groups.

Xu, Liangxuan published the artcileMomentary click nitrile synthesis enabled by an aminoazanium reagent, Computed Properties of 1205-17-0, the main research area is nitrile preparation selective Schmidt reaction aminoazanium reagent.

Momentary and selective Schmidt-type nitrile synthesis was reported. The success of this achievement was ascribed to the employment of the stable and robust aminoazanium reagent H2N-DABCO. A broad range of functionalized aldehydes were efficiently converted to nitriles within 5 min at room temperature in air. The robustness and speed of the protocol allow the CHO group to be regarded as a CN equivalent in organic synthesis. Moreover, the synthetic advantage of this developed protocol is further highlighted via the direct cyanation of a diversity of aldehyde precursors (carboxylic acids, aromatics, aryl halides, alkenes and alkynes) in a cyanide-free process. Addnl., this protocol can not only be used for rapid access to a wide range of ligands and material precursors, but it can also be used in the late-stage modification of complex bioactive mols.

Korvinson, Kirill A. published the artcileCatalytic Reductions Without External Hydrogen Gas: Broad Scope Hydrogenations with Tetrahydroxydiboron and a Tertiary Amine, Synthetic Route of 151-10-0, the main research area is arene arylamine benzylic alc chemoselective preparation; palladium catalyst reduction haloarene aryl triflate without hydrogen; hydroxydiboron methylmorpholine chemoselective reductant; chemoselective deuteration haloarene palladium catalyst deuterated hydroxyboron DMAP; deuteriation; diboron; hydrogenation; reduction; tetrahydroxydiboron.

Aryl bromides, iodides, chlorides, and triflates, benzylic halides and ethers, benzyl carbamates, alkenes, alkynes, azides, and aldehydes underwent reductive cleavage, hydrogenation, and reduction reactions using B2(OH)4 as reductant in the presence of Pd/C and 4-methylmorpholine. Aryl dihalides containing two different halogen atoms underwent selective reduction, with reduction of I favored over reduction of Br and Cl, and Br reduction favored over the reduction of Cl. Cyano groups were unaffected, but nitro group and ketones underwent reduction to a low extent. B2(OD)4 and N,N-bis(methyl-d3)pyridin-4-amine (DMAP-d6) were used as reagents for the reductive deuteration of aryl halides. Hydrogen gas has been observed to form with this reagent combination.

Pan, Gao-Fei published the artcileSynthesis of Enones and Enals via Dehydrogenation of Saturated Ketones and Aldehydes, Product Details of C11H12O3, the main research area is enone enal preparation; ketone aldehyde dehydrogenation palladium catalyst.

A general, efficient and economic palladium-catalyzed dehydrogenation to form enones or enals has been developed. The approach possesses extremely broad substrate scope including various linear or cyclic saturated ketones and aldehydes. The protocol is ligand-free, and mol. oxygen is used as the sole clean oxidant in the reaction. Due to mild reaction conditions, good functional group compatibility, and versatile utilities of enones and enals, the method can be applied in the late-stage synthesis of natural products, pharmaceuticals and fine chems.

Lan, Liyuan published the artcilePreparation and odor characteristics of nitriles derived from aldehydes, HPLC of Formula: 1205-17-0, the main research area is aldehyde hydroxylamine hydrochloride reaction; aldoxime preparation dehydration; nitrile preparation odor.

Twenty nitriles, including saturated and unsaturated aliphatic, araliph., and aromatic nitriles, were prepared from the corresponding aldehydes, commonly used as flavors or fragrances. The aldehydes were converted to aldoximes first, which then underwent dehydration by treatment with oxalyl chloride in the presence of a catalytic amount of DMSO. The nitriles were obtained in high yields in most cases. The odor characteristics of the nitriles obtained were evaluated by GC-O. The nitriles present varied characteristic odors, which are usually distinct from those of the corresponding aldehydes.
