Bicyclic (alkyl)(amino)carbene (BICAAC) as a metal-free catalyst for reduction of nitriles to amines

Bicyclic (alkyl)(amino)carbene (BICAAC) is introduced as a metal-free catalyst for the reduction of various nitriles to the corresponding amine hydrochloride salts in the presence of pinacolborane. Mechanistic investigations combining experiments and DFT calculations suggest a B-H addition to the carbene center, which acts as a carrier of the hydride source. This journal is

Catalytic Staudinger Reduction at Room Temperature

We report an efficient catalytic Staudinger reduction at room temperature that enables the preparation of a structurally diverse set of amines from azides in excellent yields. The reaction is based on the use of catalytic amounts of triphenylphosphine as a phosphine source and diphenyldisiloxane as a reducing agent. Our catalytic Staudinger reduction exhibits a high chemoselectivity, as exemplified by reduction of azides over other common functionalities, including nitriles, alkenes, alkynes, esters, and ketones.

Reusable Nickel Nanoparticles-Catalyzed Reductive Amination for Selective Synthesis of Primary Amines

The preparation of nickel nanoparticles as efficient reductive amination catalysts by pyrolysis of in situ generated Ni-tartaric acid complex on silica is presented. The resulting stable and reusable Ni-nanocatalyst enables the synthesis of functionalized and structurally diverse primary benzylic, heterocyclic and aliphatic amines starting from inexpensive and readily available carbonyl compounds and ammonia in presence of molecular hydrogen. Applying this Ni-based amination protocol, -NH2 moiety can be introduced in structurally complex compounds, for example, steroid derivatives and pharmaceuticals.

Efficient hydrogenation of benzaldoximes and Schiff bases on ceramic high-porosity palladium catalysts

An efficient catalytic method for the synthesis of benzyl- and dibenzylamines by hydrogenating oximes and Schiffbases was developed on palladium supported high-porosity foamed ceramic block catalyst. The multiple regeneration ability of the foamed ceramic block catalyst can significantly decrease the Pd consumption as compared to the use of the conventional 10%Pd/C catalyst. Owing to a high hardness of the foamed ceramic catalyst, the reaction mixture can rapidly be removed from the reactor without using filtering devices. The structures produced by the reaction are fragments of biologically active and natural molecules. Antiproliferative properties of dibenzylamines revealed on the sea urchin embryo model suggest that these compounds can be considered as promising agents for the design of new anticancer drugs.

Rapid Continuous Ruthenium-Catalysed Transfer Hydrogenation of Aromatic Nitriles to Primary Amines

A continuous flow method for the selective reduction of aromatic nitriles to the corresponding amine is reported. The method is based on a ruthenium-catalysed transfer-hydrogenation process, requires no additives, and uses isopropanol as both solvent and reducing agent. The process utilizes 1 mol% of the commercially available [Ru(p -cymene)Cl 2 ] 2, with a residence time of ca. 9 min, and a throughput of 50 mmol/h. The method was successfully applied to a range of aromatic nitriles providing the corresponding primary amines in good yields.
