Gonzalez-Lainez, Miguel;Jimenez, M. Victoria;Azpiroz, Ramon;Passarelli, Vincenzo;Modrego, F. Javier;Perez-Torrente, Jesus J. research published 《 N-Methylation of Amines with Methanol Catalyzed by Iridium(I) Complexes Bearing an N,O-Functionalized NHC Ligand》, the research content is summarized as follows. A set of neutral [IrBr(L₂)(κC-^tBuImCH₂PyCH₂OMe)] and cationic [Ir(L₂)(κ²C,N-^tBuImCH₂PyCH₂OMe)]PF₆ (L₂ = cod, (CO)₂) Ir(I) compounds featuring a flexible lutidine-derived polydentate ligand having NHC and -OMe as donor functions were evaluated as catalyst precursors for the N-methylation of aniline using MeOH both as a reducing agent and a C1 source. The carbonyl complexes are somewhat more active than the related diene compounds with the neutral compound [IrBr(CO)₂(κC-^tBuImCH₂PyCH₂OMe)] being the more active. A range of aromatic primary amines, including heterocyclic amines, were selectively transformed into the corresponding N-methylamino derivatives using this catalyst at a low catalyst loading (0.1 mol %) and substoichiometric amounts of Cs₂CO₃ (half equiv) as a base, in MeOH at 423 K. For aliphatic primary amines, selective N,N-dimethylation was achieved under the same catalytic conditions. The unselective deprotonation of the methylene linkers in [IrBr(CO)₂(κC-^tBuImCH₂PyCH₂OMe)] affords two isomeric neutral complexes featuring a coordinated dearomatized pyridine core, which were converted into [Ir(OMe)(CO)₂(κC-^tBuImCH₂PyCH₂OMe)] upon addition of MeOH. This compound undergoes thermal activation of a C-H bond of the tert-Bu group to give the cyclometalated Ir(I) complex [Ir(CO)₂{κ²C,C-(-CH₂Me₂C-ImCH₂PyCH₂OMe)}] featuring a bidentate C,C-coordinated NHC ligand. Mechanistic studies support a borrowing H mechanism proceeding through Ir(I) intermediates with the methoxo complex as the catalytic active species and the cyclometalated complex as the catalyst resting state. D labeling experiments demonstrated that both species are in equilibrium under catalytic conditions, which is consistent with the exhibited catalytic activity of the cyclometalated complex.

Gong, Zhimin;Qian, Li;Shao, Shuai;Fan, Bo;Peng, Jianbiao;Lu, Kun;Gao, Shixiang research published 《 Effects of solvent composition on the synthesis of polydopamine Schiff base Cu complex to activate peroxymonosulfate for methyl-paraben degradation》, the research content is summarized as follows. Solvent composition plays an important role in the synthesis of metal complex materials, but to date little work on this issue has been reported. Herein, a unique Schiff base Cu complex catalyst (DPDA-Cu-95EtOH) was designed based on polydopamine (PDA) and 3, 5-dibromosalicylaldehyde (DBSA), and the influence of H₂O added during the synthesis process on its catalytic performance towards peroxymonosulfate (PMS) activation was comprehensively investigated. Our results demonstrated that adding a small amount (5%, v:v) of H₂O to the solvent absolute ethanol (EtOH) can greatly increase the Cu loading (from 3.56 at% to 10.30 at%) on the catalyst, which significantly enhanced its catalytic ability, and promoted the removal of MeP for about 4.6 times higher than that synthesized without addition of H₂O. ESR (EPR) and quenching tests revealed that ¹O₂, OH and SO^–₄ were responsible for the degradation of Methyl-paraben (MeP). Moreover, the DPDA-Cu-95EtOH/PMS system not only showed excellent stability and reusability, but also exhibited considerable removal efficiency of MeP in real wastewater. Overall, this study provides new insights into the controllable synthesis of Schiff base metal complex used for the efficient activation of PMS to remove micropollutants in wastewater.

Gockel, Samuel N.;Lee, SangHyun;Gay, Brittany L.;Hull, Kami L. research published 《 Oxidative Three-Component Carboamination of Vinylarenes with Alkylboronic Acids》, the research content is summarized as follows. The three-component carboamination of alkenes is of significant interest due to the ease by which functionalized amines can be produced from readily available chem. building blocks. Previously, a variety of carbon-centered radical precursors have been studied as the carbon components for this reaction; however, the use of general alkyl sources has remained as an unsolved challenge. Herein we present our efforts to develop an oxidative carboamination protocol that utilizes alkylboronic acids as carbon-centered radical precursors. The presented work demonstrates 34 examples, ranging from 17 to 88% yields, with a broad scope in vinylarenes, amines, and alkylboronic acids. Preliminary mechanistic studies suggest that a single-electron oxidation of the alkylboronic acid generates a carbon-centered radical intermediate that adds across the olefin followed by C-N bond formation via Cu-mediated inner-sphere or carbocation-mediated pathways.

Gillespie, James E.;Morrill, Charlotte;Phipps, Robert J. research published 《 Regioselective Radical Arene Amination for the Concise Synthesis of ortho-Phenylenediamines》, the research content is summarized as follows. The formation of arene C-N bonds directly from C-H bonds is of great importance and there has been rapid recent development of methods for achieving this through radical mechanisms, often involving reactive N-centered radicals. A major challenge associated with these advances is that of regiocontrol, with mixtures of regioisomeric products obtained in most protocols, limiting broader utility. We have designed a system that utilizes attractive noncovalent interactions between an anionic substrate and an incoming radical cation in order to guide the latter to the arene ortho position. The anionic substrate takes the form of a sulfamate-protected aniline and telescoped cleavage of the sulfamate group after amination leads directly to ortho-phenylenediamines, key building blocks for a range of medicinally relevant diazoles. Our method can deliver both free amines and monoalkyl amines allowing access to unsym., selectively monoalkylated benzimidazoles and benzotriazoles. As well as providing concise access to valuable ortho-phenylenediamines, this work demonstrates the potential for utilizing noncovalent interactions to control positional selectivity in radical reactions.

New compounds containing thiazole and pyridinium moieties were designed and synthesized. The potency of the synthesized compounds as selective inhibitors of acetylcholinesterase (AChE), and β-amyloid aggregation (Aβ) was evaluated. Compounds 7d and 7j showed the best AChE inhibitory activities at the submicromolar concentration range (IC₅₀ values of 0.40 and 0.69μM, resp.). Most of the novel compounds showed moderate to low inhibition of butyrylcholinesterase (BChE), which is indicative of their selective inhibitory effects towards AChE. Kinetic studies using the most potent compounds 7d and 7j confirmed a mixed-type of AChE inhibition mechanism in accordance with the docking results, which shows their interactions with both catalytic active (CAS) and peripheral anionic (PAS) sites. The specific binding of 7a, 7j, and 7m to PAS domain of AChE was also confirmed exptl. In addition, 7d and 7j were able to show β-amyloid self-aggregation inhibitory effects (20.38 and 42.66% resp.) stronger than donepezil (14.70%) assayed at 10μM concentration Moreover, compounds 7j and 7m were shown to be effective neuroprotective agents in H₂O₂-induced oxidative stress on PC₁₂ cells almost similar to those observed for donepezil.
