Muralirajan, Krishnamoorthy published the artcileExploring the Structure and Performance of Cd-Chalcogenide Photocatalysts in Selective Trifluoromethylation, Safety of 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde, the main research area is trifluoromethylated arene oxindole alkene preparation photochem; heteroarene alkene selective trifluoromethylation cadmium selenide catalyst.

The field of heterogeneous photoredox catalysis has grown substantially and impacted organic synthesis because of the affordability and reusability of catalysts. This study reports radical trifluoromethylation with Cd-chalcogenide semiconductors. Cd semiconductors, particularly CdSe, are readily available, com., visible-light-responsive, heterogeneous photocatalysts. The potential of readily available Cd semiconductors, particularly CdSe, is confirmed by their increased photocatalytic activity toward trifluoromethylation with various substrates, such as (hetero)arenes and vinylic amides/acids, via addition, cyclization, and decarboxylation under visible light. The economic significance of this strategy is also highlighted through the scalable synthesis of biol. active mols. followed by catalyst reuse. Moreover, these catalysts are relatively inexpensive compared with transition metal-based homogeneous photocatalysts, presently used in organic synthesis.

Kim, Myeong Jin published the artcileOxoammonium salt-mediated oxidative nitriles synthesis from aldehydes with ammonium acetate, Category: isoquinoline, the main research area is nitrile preparation; aldehyde ammonium acetate oxoammonium salt oxidation.

An efficient and scalable route for the synthesis of nitriles I [R = n-heptyl, cyclohexyl, 4-MeOC6H4, 2-thienyl, etc.] was developed by oxoammonium salt (4-acetamido-2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate) mediated oxidative conversion of aldehydes with ammonium acetate (NH4OAc). A variety of aliphatic aldehydes as well as benzaldehydes were converted into the corresponding nitriles in high yields. The nitroxyl radical which was the reduced species of the used oxoammonium salt was recovered by simple acid-base extraction for the recycling.

Higham, Joe I. published the artcileCopper catalysed oxidative α-sulfonylation of branched aldehydes using the acid enhanced reactivity of manganese(IV) oxide, Recommanded Product: 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde, the main research area is alpha sulfonyl aldehyde preparation; branched aldehyde sulfinate salt oxidative sulfonylation copper catalyst.

The oxidative coupling of secondary aldehydes and sulfinate salts is achieved using copper catalysis to form α-sulfonyl aldehydes. The use of an acidic co-solvent is important to adjust the oxidation potential of MnO2 as an oxidant. A broad range of sulfonylated aldehydes is prepared, and their further functionalisation is demonstrated. A dual ionic/radical pathway mechanism is proposed.

Das, Kuhali published the artcileManganese-Catalyzed Anti-Markovnikov Hydroamination of Allyl Alcohols via Hydrogen-Borrowing Catalysis, Formula: C11H12O3, the main research area is amino alc preparation regioselective chemoselective; allyl alc amine anti Markovnikov hydroamination manganese catalyst.

In this article, a selective formal anti-Markovnikov hydroamination of allyl alcs. RCH=C(R1)C(R2)OH (R = H, Me, n-Pr, pent-4-en-1-yl; R1 = H, Me; R2 = H, Me, Ph, furan-2-yl, etc.) is presented. It enables the versatile synthesis of valuable γ-amino alc. building blocks e.g., 3-(methyl(phenyl)amino)propan-1-ol. A phosphine-free Earth’s abundant manganese(I) complex catalyzed the reaction under hydrogen-borrowing conditions. A vast range of amines such as pyrrolidine, aniline, 1H-indoline, morpholine, etc. drug mols., and natural product derivs e.g., I. underwent successful hydroamination with primary and secondary allylic alcs. with excellent functional group tolerance. The catalysis could be performed on a gram scale and has been applied for the synthesis of drug mols. The mechanistic studies revealed the metal-ligand bifunctionality as well as hemilability of the ligand backbone as the key design principle for the success of this catalysis.

Yu, Rongrong published the artcileRegio-, Chemo-, and Enantioselective Ni-Catalyzed Hydrocyanation of 1,3-Dienes, Formula: C11H12O3, the main research area is nitrile preparation regioselective chemoselective enantioselective; diene hydrocyanation nickel catalyst.

A regio-, chemo-, and enantioselective nickel-catalyzed hydrocyanation of 1,3-dienes e.g., 1-[(1E)-buta-1,3-dien-1-yl]-4-fluorobenzene is reported. The key to the success of this asym. transformation is the use of a specific multichiral diphosphite ligand. In addition to aryl-substituted 1,3-dienes, highly challenging aliphatic 1,3-diene substrates can also be preferentially converted to the corresponding 1,2-adducts e.g., (2R,3E)-4-(4-fluorophenyl)-2-methylbut-3-enenitrile in decent yields with the highest enantioselectivities to date.

Zhang, Qi published the artcileCatalytic Asymmetric Disulfuration by a Chiral Bulky Three-Component Lewis Acid-Base, Application In Synthesis of 1205-17-0, the main research area is dicarbonyl disulfide methoxy Lewis acid base asym disulfuration; disulfide keto stereoselective preparation; chiral primary amines; disulfuration; enamines; frustrated Lewis pairs; organocatalysis.

A three-component Lewis acid-base (Lewis trio) involving a bulky chiral primary amine, B(C6F5)3 and a bulky tertiary amine has been developed as an effective enamine catalyst for enantioselective disulfuration reactions. The bulky tertiary amine was found to activate a bulky primary-tertiary diamine-borane Lewis pair for enamine catalysis via frustrated interaction. The resulted chiral bulky Lewis trio (BLT) allows for the construction of chiral disulfides via direct disulfuration with β-ketocarbonyls or α-branched aldehydes in a practical and highly stereocontrolled manner.

Lang, Simon B. published the artcileActivation of Alcohols with Carbon Dioxide: Intermolecular Allylation of Weakly Acidic Pronucleophiles, SDS of cas: 1205-17-0, the main research area is nitroalkane allyl alc carbon dioxide palladium allylation catalyst; nitrile allyl alc carbon dioxide palladium allylation catalyst; aldehyde allyl alc carbon dioxide palladium allylation catalyst; allylated product preparation.

The direct coupling of allyl alcs. with nitroalkanes, nitriles, and aldehydes using catalytic Pd(PPh3)4 has been accomplished via activation of C-OH bonds with CO2. The in situ formation of carbonates from alcs. and CO2 facilitates oxidative addition to Pd to form reactive π-allylpalladium intermediates. In addition, the formation of a strong base activates nucleophiles toward the reaction with the π-allylpalladium electrophile. Overall, this atom economical reaction provides a new C-C bond without the use of an external base and generates water as the only byproduct.

Pan, Gao-Fei published the artcileAn efficient Pd@Pro-GO heterogeneous catalyst for the α, β-dehydrogenation of saturated aldehyde and ketones, Recommanded Product: 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde, the main research area is aldehyde ketone dehydrogenation palladium proline graphene oxide catalyst; enal enone preparation Saegusa oxidation.

An Efficient Pd@Pro-GO heterogeneous catalyst was developed that can promote the α, β-dehydrogenation of saturated aldehyde and ketones in the yield of 73% – 92% at mild conditions without extra oxidants and additives. Pd@Pro-GO heterogeneous catalyst was synthesized via two steps: firstly, the Pro-GO was obtained by the esterification reaction between graphene oxide (GO) and N-(tert-Butoxycarbonyl)-L-proline (Boc-Pro-OH), followed by removing the protection group tert-Butoxycarbonyl (Boc), which endowed the proline-functionalized GO with both the lewis acid site (COOH) and the bronsted base site (NH), besides, the pyrrolidine of proline also can form imine with aldehydes to activate these substrates; Second, palladium was dispersed on the proline-functionalized GO (Pro-GO) to obtained heterogeneous catalyst Pd@Pro-GO. Mechanistic studies have shown that the Pd@Pro-GO-catalyzed α,β-dehydrogenation of saturated aldehyde and ketones was realized by an improved heterogeneously catalyzed Saegusa oxidation reaction. Based on the above characteristics, the Pd@Pro-GO will be widely used in the transition metal catalytic field.
