Many nitrogen compounds can thus be potentially but its degree depends on the configuration: the nitrogen atom in is not basic due to delocalization of the lone pair into a double bond and in the lone pair is part of an aromatic sextet.Carbonnitrogen bond...
The electroreduction of CO2is a promising technology for carbon utilization. Although electrolysis of CO2or CO2-derived CO can generate important industrial multicarbon feedstocks such as ethylene, ethanol,n-propanol and acetate, most efforts have been devoted to promoting C–C bond formation. Here, ...
A second aspect of the present invention relates to the use of catalysts comprising these ligands in various transition-metal-catalyzed carbon-heteroatom and carbon-carbon bond-forming reactions. The subject methods provide improvements in many features of the transition-metal-catalyzed reactions, ...
So, it's not so much that nitrogen is special and carbon isn't. It's true that the nitrogen bonds are slightly stronger than the carbon bonds, but that is not really a factor here. The main issue is that you're comparing two different things (formation of a f...
Addition of Acid Anhydrides to the Nitrogen-Carbon Double Bond of Isoquinoline Rings The rhodium-catalyzed intramolecular direct arylation of imidazole and benzimidazole derivatives via double C-H bond activation is described. This approach... Yamanaka,Hiroshi,Shiraishi,... - 《Heterocycles》 被引量: ...
Polydentate complexes containing combinations of nitrogen and carbon (N and C) ligating atoms are among the most fundamental and ubiquitous molecules in coordination chemistry, yet the formation of such complexes with planar high-coordinate N/C sites rem
Elemental nitrogen can be used as an inert atmosphere for reactions requiring the exclusion of oxygen and moisture. In the liquid state, nitrogen has valuable cryogenic applications; except for the gases hydrogen, methane, carbon monoxide, fluorine, and oxygen, practically all chemical substances have...
Stored energy: Rendition of a system that combines polymeric nitrogen (blue chain) and carbon nanotube (clear spheres). (Courtesy: Heba Megahd) From TNT to nitro-glycerine, nitrogen-rich compounds are known for packing an explosive punch. When these materials explode, bonds between atoms in the...
Measurements of the D (R NO) bond strength in some C-nitrosocompounds have been made using an electron impact method. The appearance potential of the radical ion (R + ) has been determined, the D (R NO) bond energy being obtained from the relation The values obtained are: D (C 6 H...
Other classes of nitrogen anions (negatively charged ions) are the poisonous azides (N−3), which are linear and isoelectronic to carbon dioxide, but which bind to important iron-containing enzymes in the body in a manner more resembling cyanide. Another molecule of the same structure is the...
