Via an imine-protection strategy, the authors herein present an unprecedented copper-catalyzed oxidative multicomponent annulation reaction for direct synthesis of quinazolinones. The construction of various products is achieved via formation of three C-N and one C-C bonds in conjunction with the benzylic functionalization. The merits of easily available feedstocks, naturally abundant catalyst, good functional group and substrate compatibility, and release of H2O as the byproduct make the developed chem. a practical way to access quinazolinones.

An I2O5 promoted tandem Strecker/C(sp3)-H amination reaction of pyridine-2-carboxaldehydes, benzylamines and NH4SCN was reported. This multicomponent reaction that allowed the single-step construction of biol. important cyano-functionalized imidazo[1,5-a]pyridines with mol. diversity was realized for the first time. Moreover, the use of safe and easy-to-handle NH4SCN as a surrogate cyanating agent made this protocol appealing for potential applications.

Xie, Chao; Song, Jinliang; Hua, Manli; Hu, Yue; Huang, Xin; Wu, Haoran; Yang, Guanying; Han, Buxing published the artcile< Ambient-Temperature Synthesis of Primary Amines via Reductive Amination of Carbonyl Compounds>, Recommanded Product: 4-Bromobenzylamine, the main research area is primary amine preparation reductive amination titanium phosphate Ruthenium nanocatalyst.

Efficient synthesis of primary amines via low-temperature reductive amination of carbonyl compounds using NH3 and H2 as the nitrogen and hydrogen resources is highly desired and challenging in the chem. community. Herein, we employed naturally occurring phytic acid as a renewable precursor to fabricate titanium phosphate (TiP)-supported Ru nanocatalysts with different reduction degrees of RuO2 (Ru/TiP-x, x represents the reduction temperature) by combining ball milling and molten-salt processes. Very interestingly, the obtained Ru/TiP-100 had good catalytic performance for the reductive amination of carbonyl compounds at ambient temperature, resulting from the synergistic cooperation of the support (TiP) and the Ru/RuO2 with a suitable proportion of Ru0 (52%). Various carbonyl compounds could be efficiently converted into the corresponding primary amines with high yields. More importantly, the conversion of other substrates with reducible groups could also be achieved at ambient temperature Detailed investigations indicated that the partially reduced Ru and the support (TiP) were indispensable. The high activity and selectivity of Ru/TiP-100 catalyst originates from the relatively high acidity and the suitable electron d. of metallic Ru0.

Formenti, Dario; Mocci, Rita; Atia, Hanan; Dastgir, Sarim; Anwar, Muhammad; Bachmann, Stephan; Scalone, Michelangelo; Junge, Kathrin; Beller, Matthias published the artcile< A State-of-the-Art Heterogeneous Catalyst for Efficient and General Nitrile Hydrogenation>, Related Products of 3959-07-7, the main research area is cobalt doped carbon metal oxide catalyst preparation surface area; nitrile cobalt doped carbon metal oxide catalyst hydrogenation; amines; cobalt; heterogeneous catalysis; hydrogenation; magnesium oxide.

Cobalt-doped hybrid materials consisting of metal oxides and carbon derived from chitin were prepared, characterized and tested for industrially relevant nitrile hydrogenations. The optimal catalyst supported onto MgO showed, after pyrolysis at 700°C, magnesium oxide nanocubes decorated with carbon-enveloped Co nanoparticles. This special structure allows for the selective hydrogenation of diverse and demanding nitriles to the corresponding primary amines under mild conditions (e.g. 70°C, 20 bar H2). The advantage of this novel catalytic material is showcased for industrially important substrates, including adipodinitrile, picolinonitrile, and fatty acid nitriles. Notably, the developed system outperformed all other tested com. catalysts, for example, Raney Nickel and even noble-metal-based systems in these transformations.
