Niknam, Esmaeil published the artcilePalladium-Catalyzed Cyanation of Aryl Halides Using Formamide and Cyanuric Chloride as a New “”CN”” Source, Recommanded Product: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is aryl halide cyanuric chloride formamide palladium cyanation catalyst; cyanide aryl preparation.

A new source of “”CN”” employing formamide and cyanuric chloride is introduced for the cyanation reactions. The treatment of formamide and 2,4,6-trichloro-1,3,5-triazine (TCT; cyanuric chloride) afforded an efficient cyanating agent which it can be used as a nontoxic, readily available, and non-expensive reagent in the cyanation transformations. In this study, palladium-catalyzed cyanation of aryl halides was successfully accomplished using this new “”CN”” source in high yields.

Yan, Yonggang published the artcilePhotochemically Enabled, Ni-Catalyzed Cyanation of Aryl Halides, Recommanded Product: Phthalonitrile, the main research area is dicyanobenzene haloarene nickel catalyst photochem cyanation; aryl nitrile preparation.

A light-promoted Ni-catalyzed cyanation of aryl halides employing 1,4-dicyanobenzene as a cyanating agent was reported. A broad array of aryl bromides, chlorides and druglike mols. could be converted into their corresponding nitriles (65 examples). Mechanistic studies suggest that upon irradiation, the oxidative addition product Ni(II)(dtbbpy)(p-C6H4CN)(CN) underwent homolytic cleavage of the Ni-aryl bond to generate an aryl radical and a Ni(I)-CN species, the latter of which initiated subsequent cyanation reactions.

Nasrollahzadeh, Mahmoud published the artcileSynthesis, characterization and catalytic performance of Pd(II) complex immobilized on Fe3O4@SiO2 nanoparticles for the ligand-free cyanation of aryl halides using K4Fe(CN)6, Recommanded Product: Phthalonitrile, the main research area is reusable iron oxide supported palladium nanocatalyst preparation surface area; potassium ferrocyanate aryl halide reusable palladium nanocatalyst cyanation; aryl nitrile preparation green chem.

The preparation of a novel magnetic catalyst via immobilization of Pd(II)-N-benzyl-N-(4-bromophenyl)-5-amino-1H-tetrazole complex on the Fe3O4@SiO2 nanoparticles (NPs). The application of Fe3O4@SiO2 NPs supported Pd(II)-N-benzyl-N-(4-bromophenyl)-5-amino-1H-tetrazole complex [Fe3O4@SiO2-BAT-Pd(II)] nanocatalyst was described for the cyanation of aryl iodides and bromides to the corresponding aryl nitriles using potassium hexacyanoferrate(II) [K4Fe(CN)6] as a non-toxic and economic cyanating agent under ligand- and additive-free conditions. Some aryl nitriles were efficiently synthesized from the corresponding aryl bromides and iodides in the presence of Fe3O4@SiO2-BAT-Pd(II) nanocomplex. The core-shell nanocomplex demonstrated the superior catalytic performance for the synthesis of synthetically valuable aryl nitriles within good to excellent yields. This process eliminated the need to handle highly toxic metal cyanides and it was easily recovered and reused for six consecutive runs with no decreasing of its catalytic capability.

Shee, Maniklal published the artcileOrganophotoredox assisted cyanation of bromoarenes via silyl-radical-mediated bromine abstraction, Quality Control of 91-15-6, the main research area is organophotoredox catalyzed cyanation bromoarene silyl radical bromine abstraction.

The insertion of a nitrile (-CN) group into arenes through the direct functionalization of the C(sp2)-Br bond is a challenging reaction. Herein, we report an organophotoredox method for the cyanation of aryl bromides using the organic photoredox catalyst 4CzIPN (1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene) and tosyl cyanide (TsCN) as the nitrile source. A photogenerated silyl radical, via a single electron transfer (SET) mechanism, was employed to abstract bromine from aryl bromide to provide an aryl radical, which was concomitantly intercepted by TsCN to afford the aromatic nitrile. A range of substrates containing electron-donating and -withdrawing groups was demonstrated to undergo cyanation at room temperature in good yields. Thus, e.g., Me 4-bromobenzoate �Me 4-cyanobenzoate (71%) employing 4CzIPN, TsCN, (TMS)3SiOH as silyl radical source, K3PO4 as base, acetone as solvent and irradiation from blue LED.

Nandi, Ganesh C. published the artcileSchmidt reaction in ionic liquids: highly efficient and selective conversion of aromatic and heteroaromatic aldehydes to nitriles with [BMIM(SO3H)][OTf] as catalyst and [BMIM][PF6] as solvent, HPLC of Formula: 5653-62-3, the main research area is Schmidt reaction aromatic aldehyde ionic liquid catalyst solvent.

A mild and selective method is presented for the conversion of aromatic and heteroaromatic aldehydes to nitriles via the Schmidt reaction with TMSN3 by using [BMIM(SO3H)][OTf] as catalyst and [BMIM][PF6] as solvent. E.g., in the presence of this catalyst in [BMIM][PF6], reaction of 2-MeOC6H4CHO with TMSN3 gave 100% 2-MeOC6H4CN. The method offers high yields and simple product isolation, and avoids the use of liquid superacids or corrosive Lewis acids commonly employed for this transformation. It also offers some potential for recycling/reuse of the IL solvent.

Meng, Hong published the artcileIron and Phenol Co-Catalysis for Rapid Synthesis of Nitriles under Mild Conditions, Category: nitriles-buliding-blocks, the main research area is nitrile preparation; aldehyde oxime ester oxidation iron phenol catalyst.

A mild, scalable, high yielding, and rapid route to access diverse nitriles from aldehyde oxime esters enabled by iron(III) and phenol co-catalysis has been developed. The reaction was performed at room temperature to give nitriles in excellent yield within minutes. Mechanistic studies show that the reaction may proceed through a radical process in which benzoyl aldehyde oxime is not only a substrate, but also an ancillary ligand to support iron salt in the promotion of the transformation.
