A highly selective N-monomethylation of aniline and nitrobenzene using methanol as methylating reagent was achieved with high efficiency when using an encapsulated iridium nanocatalyst. A wide range of amines and nitro compounds reacted well in the established catalytic system with moderate to excellent product yields and good functional group tolerance. The transfer hydrogenation and successive cyclization coupling reaction of ortho-phenylenediamine with methanol to afford benzimidazole and N-methylbenzimidazole was also efficiently realized under moderate reaction conditions. Recycling experiments showed that the iridium nanocatalyst had a good stability without obvious activity loss.

Huang, Ming published the artcileRuthenium(II) complexes with N-heterocyclic carbene-phosphine ligands for the N-alkylation of amines with alcohols, COA of Formula: C8H11NO, the main research area is secondary arylamine preparation; amine alc alkylation ruthenium phosphine ligand catalyst.

Metal hydride complexes are key intermediates for N-alkylation of amines with alcs. by the borrowing hydrogen/hydrogen autotransfer (BH/HA) strategy. Reactivity tuning of metal hydride complexes could adjust the dehydrogenation of alcs. and the hydrogenation of imines. Herein we report ruthenium(II) complexes with hetero-bidentate N-heterocyclic carbene (NHC)-phosphine ligands, which realize smart pathway selection in the N-alkylated reaction via reactivity tuning of [Ru-H] species by hetero-bidentate ligands. In particular, complex I·BArF- with a Ph wingtip group and BArF- counter anion, is shown to be one of the most efficient pre-catalysts for this transformation (temperature is as low as 70°C, neat conditions and catalyst loading is as low as 0.25 mol%). A large variety of (hetero)aromatic amines and primary alcs. were efficiently converted into mono-N-alkylated amines in good to excellent isolated yields. Notably, aliphatic amines, challenging methanol and diamines could also be transformed into the desired products. Detailed control experiments and d. functional theory (DFT) calculations provide insights to understand the mechanism and the smart pathway selection via [Ru-H] species in this process.

Sagadevan, Arunachalam published the artcileCopper Photoredox Catalyzed A3′ Coupling of Arylamines, Terminal Alkynes, and Alcohols through a Hydrogen Atom Transfer Process, Category: isoquinoline, the main research area is propargylamine preparation; alkylaniline terminal alkyne alc three component coupling; hydrogen atom transfer photoredox copper catalyst; amines; copper; photochemistry; radicals; synthetic methods.

The first successful example of the three-component coupling of N-alkylanilines, terminal alkynes, and alcs. was achieved at room temperature by a visible-light-mediated copper-catalyzed photoredox hydrogen-atom transfer process. This method allows preparation of propargylamines I (R1 = H, 4-Me, 3-I, etc.; R2 = Me, n-Bu, Bn, etc.; R3 = C6H5, 3-MeC6H4, 3-thienyl, etc.; R4 = H, Me, c-Pr, etc.) through uniquely selective α-C-H bond activation of unactivated alkylalcs. Preliminary studies indicate that formation of α-oxy radical is operative. This approach facilitates rapid access to biol. important propargylamines from methanol as an abundant feedstock.

Donthireddy, S. N. R. published the artcileRuthenium(II) Complexes of Heteroditopic N-Heterocyclic Carbene Ligands: Efficient Catalysts for C-N Bond Formation via a Hydrogen-Borrowing Strategy under Solvent-Free Conditions, Safety of 4-Methoxy-N-methylaniline, the main research area is ruthenium imidazolylidene triazolylidene complex preparation crystal structure benzylation catalyst; crystal structure ruthenium imidazolylidene triazolylidene complex; mol structure ruthenium imidazolylidene triazolylidene complex; benzyl alc coupling reaction benzylation aniline derivative carbeneruthenium catalyst; quinoline derivative preparation.

Both imidazol-2-ylidene (ImNHC) and 1,2,3-triazol-5-ylidene (tzNHC) have evolved to be elite groups of N-heterocyclic carbene (NHC) ligands for homogeneous catalysis. To develop efficient Ru(II)-based catalysts incorporating these ligands for C-N bond-forming reactions via H-borrowing methodol., the authors used chelating ligands integrated with ImNHC and mesoionic tzNHC donors connected via a CH2 spacer with a diverse triazole backbone. The synthesized Ru(II) complexes 3 are highly efficient for C-N bond formation across a wide range of primary amine and alc. substrates under solvent-free conditions, and among all of the complexes studied here, catalyst 3a with a mesityl substituent displayed maximum activity. Catalyst 3a is also effective for the selective mono-N-methylation of various anilines using MeOH as a coupling partner, known to be relatively more difficult than other alcs. Also, complex 3a also delivers various substituted quinolines successfully via the reaction of 2-aminobenzyl alc. with several secondary alcs. Importantly, catalyst 3a exhibited the highest activity among the reported Ru(II) complexes for both the N-benzylation of aniline [achieving a turnover number (TON) of 50000] and the realization of quinoline 8a by reacting 2-aminobenzyl alc. with 2-phenylethanol (attaining a TON of 30000). The significance of electronic tuning in the Ru(II) complexes of chelating ligands featuring a combination of ImNHC and tzNHC donors with various triazole backbones is demonstrated by applying them in diverse C-N bond-forming reactions via a H-borrowing strategy. Notably, the Ru(II) complex 3a having an N-mesityl substituent displayed the highest activity among known Ru(II) complexes for both the N-benzylation of aniline [a turnover number (TON) of 50000] and the synthesis of quinoline via the reaction of 2-aminobenzyl alc. with 2-phenylethanol (a TON of 30000).

Wang, Tao published the artcileA Metal-Free Direct Arene C-H Amination, Related Products of isoquinoline, the main research area is aryl amine preparation chemoselective; arene hydroxylamine amination.

Here, a metal-free arene e.g., mesitylene C-H amination using hydroxylamine derivatives 4-(CH3)C6H5S(O)2ON(R)R1 (R = H, Me; R1 = Me, Boc, Bn, etc.) under benign conditions was reported. A charge transfer interaction between the aminating reagents and the arene substrates enables the chemoselective amination of the arene, even in the presence of various functional groups. Oxygen was crucial for an effective conversion and its accelerating role for the electron transfer step was proven exptl. In addition, this was rationalized by a theor. study which indicated the involvement of a dioxygen-bridged complex with a “”Sandwich-like”” arrangement of the aromatic starting materials and the aminating agents at the dioxygen mol.

Piehl, Patrick published the artcileEfficient methylation of anilines with methanol catalysed by cyclometalated ruthenium complexes, Synthetic Route of 5961-59-1, the main research area is methylaniline preparation; aniline methanol methylation ruthenium complex catalyst.

Cyclometalated ruthenium complexes, e.g., I, allow the effective methylation of anilines (R = 4-bromophenyl, 2-methylphenyl, 4-carbamoylphenyl, etc.) with methanol to selectively give N-methylanilines RNHCH3. This hydrogen autotransfer procedure proceeds under mild conditions (60°C) in a practical manner (NaOH as base). Mechanistic investigations suggest an active homogenous ruthenium complex and β-hydride elimination of methanol as the rate determining step.
