Nature of the Nucleophilic Oxygenation Reagent Is Key to Acid-Free Gold-Catalyzed Conversion of Terminal and Internal Alkynes to 1,2-Dicarbonyls

2,3-Dichloropyridine N-oxide, a novel oxygen transfer reagent, allows the conductance of the gold(I)-catalyzed oxidation of alkynes to 1,2-dicarbonyls in the absence of any acid additives and under mild conditions to furnish the target species, including those derivatized by highly acid-sensitive groups. The developed strategy is effective for a wide range of alkyne substrates such as terminal- and internal alkynes, ynamides, alkynyl ethers/thioethers, and even unsubstituted acetylene (40 examples; yields up to 99%). The oxidation was successfully integrated into the trapping of reactive dicarbonyls by one-pot heterocyclization and into the synthesis of six-membered azaheterocycles. This synthetic acid-free route was also successfully applied for the total synthesis of a natural 1,2-diketone.

Robust cyclometallated Ir(iii) catalysts for the homogeneous hydrogenation of N-heterocycles under mild conditions

Cyclometallated Cp*Ir(N?C)Cl complexes derived from N-aryl ketimines are highly active catalysts for the reduction of N-heterocycles under ambient conditions and 1 atm H2 pressure. The reaction tolerates a broad range of other potentially reducible functionalities and does not require the use of specialised equipment, additives or purified solvent.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Electric Literature of 6344-72-5. In my other articles, you can also check out more blogs about 6344-72-5

Nickel-catalyzed electrochemical Minisci acylation of aromatic N-heterocycles with alpha-keto acids via ligand-to-metal electron transfer pathway

A nickel-catalyzed electrochemical methodology for the Minisci acylation of aromatic electron-deficient heterocycles with alpha-keto acids has been developed. The reaction is performed in an undivided cell under constant current conditions, featuring broad scope of substrates and avoiding the conventional utilization of silver-based catalysts in conjunction with excess amount of oxidants. Cyclic voltammetric analysis disclosed that a ligand-to-metal electron transfer process may be involved in the generation of the key acyl radicals.

Photoinduced Nitro-Nitrite Rearrangement of 5-Nitroquinoxalines

Unlike known o-nitro methyl derivatives of aromatic compounds, 6-methyl-5-nitro-, 2,3,6-trimethyl-5-nitro-, and 7-methyl-6-nitroquinoxaline and 1,6-dimethyl-5-nitroquinoxalinium perchlorate do not exhibit photochromism in aqueous-ethanolic solutions under conditions of flash photolysis with a time resolution of 50 mus. Under conditions of continuous photolysis, these 5-nitromethylquinoxaline derivatives and also 5-nitroquinoxaline undergo nitro-nitrite rearrangement to give 5-quinoxalinol derivatives with quantum yields ranging from 1 ¡Á 10-4 to 3 ¡Á 10-3; the efficiency of the photochemical reaction increases when irradiation is performed with a shorter-wave light. 6-Nitro derivatives do not form stable products of photochemical transformations under the same conditions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 6344-72-5, you can also check out more blogs about6344-72-5

A green synthesis of quinoxalines and 2,3-dihydropyrazines

Quinoxaline and dihydropyrazine derivatives were obtained in high yields by simple addition of 1,2-diamines and 1,2-dicarbonyl compounds in water. In some cases, the products spontaneously precipitated from the reaction mixture, making it possible to recover and reuse the mother liquor for further condensations. The very mild reaction conditions, the high yields of the products, and the absence of any catalyst make this methodology an efficient and green route to quinoxalines and dihydropyrazines.
