Herein, the use of potassium permanganate as an oxidant to synthesize 3-amino-7-(N, N-dimethylamino)-2-substituted-5-phenylphenazin-5-ium chlorides I (X = Me, Et, Br, etc.) via sequential aniline arylation is reported. The synthesized products were obtained via reaction of various o-substituted toluidines with 4-amino-N,N-dimethyamine and aniline using potassium permanganate as an oxidant under different conditions such as temperature, pH, reaction time and the ratio of raw materials. IR (IR) absorption data were acquired on a Thermo Nicolet Nexus 670 FT-IR spectrometer with DTGS KBr detector. The total C, H, N, content was measured by the elemental analyzer. The yields of the products ranging from 42.5% to 75.8% was obtained based on the electrophilic ability of different substituted groups under the temperature of 95°, pH 4.5 and the reaction time of 8hrs. This route is a simple, economic, efficient and environmentally friendly.

Bains, Amreen K. published the artcileBorrowing Hydrogen-Mediated N-Alkylation Reactions by a Well-Defined Homogeneous Nickel Catalyst, HPLC of Formula: 1885-29-6, the main research area is borrowing hydrogen mediated nitrogen alkylation aniline alc; well defined homogeneous nickel catalyzed alkylation redox active ligand.

We report herein a well-defined and bench-stable azo-phenolate ligand-coordinated nickel catalyst which can efficiently execute N-alkylation of a variety of anilines by alc. We demonstrate that the redox-active azo ligand can store hydrogen generated during alc. oxidation and redelivers the same to an in-situ-generated imine bond to result in N-alkylation of amines. The reaction has wide scope, and a large array of alcs. can directly couple to a variety of anilines. Mechanistic studies including deuterium labeling to the substrate establishes the borrowing hydrogen method from alcs. and pinpoints the crucial role of the redox-active azo moiety present on the ligand backbone. Isolation of the ketyl intermediate in its trapped form with a radical quencher and higher kH/kD for the alc. oxidation step suggest altogether a hydrogen-atom transfer (HAT) to the reduced azo backbone to pave alc. oxidation as opposed to the conventional metal-ligand bifunctional mechanism. This example clearly demonstrates that an inexpensive base metal catalyst can accomplish an important coupling reaction with the help of a redox-active ligand backbone.

Senadi, Gopal Chandru published the artcileSustainable methine sources for the synthesis of heterocycles under metal- and peroxide-free conditions, Recommanded Product: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is quinazolinone green preparation; alc amino benzamide cascade oxidative cleavage; ether amino benzamide cascade oxidative cleavage; benzimidazole green preparation; amino benzylamine methoxyethanol cascade oxidative cleavage.

Alcs. and ethers were identified as sustainable methine sources for synthesizing quinazolinones I [R = H, 8-Me, 7-NO2, etc.; R1 = OMe, allyl, Ph, etc,] and benzimidazoles II [R2 = H, 5-Cl, 6,7-di-Me, etc.] using a combination of TsOH·H2O/O2 and appropriate bis-nucleophiles for the first time. Deuterium labeling studies clearly proved that the C2 hydrogen of the synthesized heterocycles came from the methine source. These unique reaction conditions were successfully applied to the synthesis of echinozolinone I [R = H; R1 = CH2CH2OH, 2-(1H-indol-3-yl)ethyl] (a common precursor of rutaecarpine and (±) evodiamine) and dimedazole II [R2 = 5,6-di-Me]. Notable features of this method included its low toxicity, use of com. feedstocks as substrates, low cost, broad functional group tolerance and suitability for a wide range of bis-nucleophilic starting materials.

Wei, Xiangyang published the artcileDecyanative Cross-Coupling of Cyanopyrimidines with O-, S-, and N-Nucleophiles: A Route to Alkoxylpyrimidines, Aminopyrimidines and Alkylthiopyrimidines, Formula: C6H4N2, the main research area is decyanative cross coupling cyanopyrimidine alc thiol amine; preparation alkoxylpyrimidine aminopyrimidine alkylthiopyrimidine.

The transition metal-free cross-coupling reactions of cyanopyrimidines with aliphatic alcs., thiols (or S-alkylisothiourea salts) and amines, giving the corresponding alkoxylpyrimidines, aminopyrimidines, and alkylthiopyrimidines, are reported. Preliminary mechanistic studies reveal that it probably involves a sequential nucleophilic addition-intramol. rearrangement process, which is promoted by an intramol. N-H···N five-membered hydrogen bonding interaction. The presence of a nitrogen atom next to the cyano group is indispensable. The wide substrate scope with excellent yields makes cyanopyrimidines a promising alternative substrate class to the frequently used pyrimidines halides for the formation of C-O, C-S, and C-N bonds through the decyanative cross-coupling reaction.
