The cleavage and functionalization of recalcitrant carbon─carbon bonds is highly challenging but represents a very powerful tool for value-added transformation feedstock chemicals. Here, an enzyme-mimic iron single-atom catalyst (SAC) bearing (III) nitride (FeN3) motifs was prepared found to be robust cyanation carbon-carbon in secondary alcohols ketones. High nitrile yields are obtained with wide variety functional groups. FeN3-SAC exhibits high enzyme-like activity capable generating...
Catalytic ammoxidation of alcohols into nitriles is an essential reaction in organic synthesis. While highly desirable, conducting the synthesis at room temperature challenging, using NH3 as nitrogen source, O2 oxidant, and a catalyst without noble metals. Herein, we report robust photocatalysts consisting Fe(III)-modified titanium dioxide (Fe/TiO2) for reactions utilizing oxygen atmospheric pressure, NH4Br additive. To best our knowledge, this first example catalytic over photocatalyst such...
The C-N bond cleavage represents one kind of important organic and biochemical transformation, which has attracted great interest in recent years. oxidative bonds N,N-dialkylamines into N-alkylamines been well documented, but it is challenging the further primary amines due to thermally unfavorable release α-position H from N-Cα-H paralleling side reactions. Herein, a biomass-derived single Zn atom catalyst (ZnN4-SAC) was discovered be robust heterogeneous non-noble for with O2 molecules....
The development of metal-free catalytic systems is highly desirable in organic transformation. Herein, a biomass-derived carbon catalyst with high surface area was discovered to be robust for the and additive-free synthesis cyclic imides nitriles from ketones via strategy oxidative cleavage C(O)–C bonds first time, which remains kind challenging transformation even metal catalysts. Experimental data DFT calculations revealed that both defective sites oxygen-functional groups, particularly,...
Because of the highly inert aromatic ring, hydrodeoxygenation and subsequent ring hydrogenation reactions ketones into high-energy-density liquid hydrocarbons remain a great challenge even over noble metal catalysts. Herein, heterogeneous cobalt catalysts composed metallic Co nanoparticles single atoms with Co–N5 motifs were found to display excellent activity in simultaneous C═O/C–OH bonds as well hydrocarbons, where served Lewis acid sites activate activated H2 molecules. Experimental data...
Cobalt nanoparticles supported on microporous nitrogen-doped carbon (Co/mNC) were prepared for catalytic hydrogen transfer between nitroarenes and N-heterocycles.
