Main-group Element-mediated Activation Of Dinitrogen
Main-group element-mediated activation of dinitrogen is the Nitrogen activation, N2 activation facilitated by reactive main group element centered molecules (e.g., low valent main group metal calcium, dicoordinate borylene, boron radical, carbene, etc.). Background Nitrogen fixation, Dinitrogen fixation is essential for human life. Currently, the industry uses the Haber–Bosch process to convert N2 and H2 to NH3 based on the metal catalysis under very high pressure and temperature conditions. Alternative strategies that realize the transformation from N2 to NH3 under mild conditions are a long-lasting goal in chemistry. In the past decades, a number of transition-metal species have been found to bind (and even functionalize) N2. The prevalence of transition metals in dinitrogen activation is attributed to the fact that the unoccupied and occupied d orbitals could be both energetically and symmetrically accessible to accept electron density from and back donate to N2.

Nitrogen Activation
Nitrogen is a chemical element; it has Symbol (chemistry), symbol N and atomic number 7. Nitrogen is a Nonmetal (chemistry), nonmetal and the lightest member of pnictogen, group 15 of the periodic table, often called the Pnictogen, pnictogens. It is a common element in the universe, estimated at Abundance of the chemical elements, seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element chemical bond, bond to form N2, a colourless and odourless diatomic molecule, diatomic gas. N2 forms about 78% of Atmosphere of Earth, Earth's atmosphere, making it the most abundant chemical species in air. Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772 and independently by Carl Wilhelm Scheele and Henry Cavendish at about the same time. The name was suggested by French chemist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
