In the presence of [Ru(p-cymene)Cl2]2, paraformaldehyde in H2O/toluene acted as a reductant for the chemoselective reductive deamination of alkyl and aryl nitriles to yield alkyl or benzylic primary alcs. The mechanism of the reaction is studied using the characterization of reaction intermediates by mass spectrometry; dimeric ruthenium complexes are necessary to generate reduced ruthenium complexes from paraformaldehyde, while nitrile coordination generates monomeric complexes of ruthenium which reduce the nitriles to alcs.

Convenient domino protocol was developed for the synthesis of 2-arylquinazolin-4-amines by the reaction of N-(2-cyanophenyl) substituted benzimidoyl isothiocyanates with iso-Pr amine. The major advantages of this protocol are short reaction times, mild conditions, simple work up, high yields, and pure products. The efficacy of this protocol owes to the competence of synthesis, pure isolation of imidoyl isothiocyanates, and the unique structure conformation of the corresponding intermediate thiourea derivatives

Wang, Shengyu published the artcilePd@CeO2-catalyzed cyanation of aryl iodides with K4Fe(CN)6·3H2O under visible light irradiation, Category: nitriles-buliding-blocks, the main research area is aryl nitrile preparation green chem photochem; potassium ferricyanide aryl iodide cyanation palladium catalyst.

A new protocol based on the combination of the catalyst Pd@CeO2, nontoxic cyanide source K4Fe(CN)6·3H2O, and driving force visible light irradn was developed. The reaction is performed at relatively moderate temperature (55°C) and exhibits good catalytic efficiency of product aryl nitriles RCN (R = Ph, 2-nitrophenyl, thiophen-2-yl, etc.) (yields of 89.4%). Moreover, the catalyst Pd@CeO2 possesses good reusability with a slight loss of photocatalytic activity after five consecutive runs. The reaction system based on the above combination shows a wide range of functional group tolerance under the same conditions. Reaction conditions such as temperature, time, the component of catalyst, and solutions are optimized by studying cyanation of 1-iodo-4-nitrobenzene as model reaction. According to these results, the possible mechanism of Pd@CeO2-catalyzed cyanation of aryl iodides RI under visible light irradiation is proposed based on the influence of visible light on the catalyst and reactant compounds In all, an environmental and economic method for preparation of aryl nitriles from cyanation of aryl iodides based on the goal of green chem. for sustainable development was provided.

A simple procedure for the palladium-catalyzed cyanation of aryl halides is described via a nucleophilic non-toxic cyanide source, K4[Fe(CN)6] in the presence of Pd/coral reef nanocomposite as a heterogeneous catalyst; the protocol provides a useful and easy method for the synthesis of aryl nitriles that are generated from the corresponding variant aryl halides, with sodium carbonate as a base. The nanocatalyst was prepared by a biol. process using aqueous extract of leaves of Cucurbita pepo as a stabilizing and reducing agent and coral reef as a natural support, without deploying any hazardous chems. The catalyst, that is easily separable from the reaction mixture and reused multiple times, was characterized by FT-IR (Fourier-Transform IR Spectroscopy), ICP-AES (Inductively Coupled Plasma Atomic Emission Spectroscopy), XRD (X-ray Diffraction), TEM (Transmission Electron Microscopy), FE-SEM (Field Emission SEM), EDS (Energy Dispersive X-ray Spectroscopy) and elemental mapping.

Ushijima, Sousuke published the artcileOne-pot conversion of aromatic bromides and aromatics into aromatic nitriles via aryllithiums and their DMF adduct, HPLC of Formula: 5653-62-3, the main research area is aryl halide butyl lithium DMF iodine reaction; aromatic nitrile preparation.

Various aromatic bromides and iodides were smoothly converted into the corresponding aromatic nitriles in good to moderate yields by the treatment with n-butyllithium and subsequently DMF, followed by treatment with mol. iodine in aq NH3. The same treatment of typical aromatics and heteroaromatics with n-butyllithium and subsequently DMF, followed by treatment with mol. iodine in aq NH3 also provided the corresponding aromatic nitriles in good yields. Moreover, the same treatment of aromatic bromides and aromatics with half amount of DIH (1,3-diiodo-5,5-dimethylhydantoin) instead of mol. iodine worked effectively to give the corresponding aromatic nitriles, resp., in good yields. These reactions are novel and environmentally benign one-pot methods for the preparation of aromatic nitriles from aromatic bromides and aromatics, resp., through the formation of aryllithiums and their DMF adducts.

Saikia, Rakhee published the artcileAn Insight into Nitromethane as an Organic Nitrile Alternative Source towards the Synthesis of Aryl Nitriles, Product Details of C7H6N2, the main research area is nitromethane aryl halide copper catalyst cyanation DFT transition state; aryl nitrile preparation.

Directed by an unusual in situ reduction of CuII, our protocol is a simple CuI-mediated synthesis of aryl nitriles, with inexpensive and readily available nitromethane as the cyanating source, in moderate to good yields. Exhibiting a wide substrate scope, the method involves simple reaction conditions, is additive free with low catalyst loading. The plausible mechanism of cyanation of aryl halides is elucidated by a congregation of three cycles, namely the in situ reduction of CuII species by nitromethane, generation of HCN species from nitromethane and a regular organometallic pathway which releases the nitrile derivative The detail of the mechanism of generation of CN- from nitromethane is computationally validated. Our protocol holds the distinction of involving a rarely encountered CuI catalytic species as well as facile in situ generation of nucleophilic CN- to yield synthetically useful aromatic nitriles.
