The reaction has been the subject of several literature reviews. [1] [2] [3] The Nef reaction: 1. Salt of a nitroalkane 3. Ketone 4. Nitrous oxide. The reaction was reported in 1894 by the chemist John Ulric Nef, [4] who treated the sodium salt of nitroethane with sulfuric acid resulting in an 85–89% yield of nitrous oxide and at least 70% ...
Nitroethane is produced industrially by treating propane with nitric acid at 350–450 °C. This exothermic reaction produces four industrially significant nitroalkanes: nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane. The reaction involves free radicals, such as CH 3 CH 2 CH 2 O., which arise via homolysis of the corresponding ...
A neutralization reaction is a type of double replacement reaction. A neutralization reaction occurs when an acid reacts with an equal amount of a base. This reaction usually produces a salt. One example, hydrochloric acid reacts with disodium iron tetracarbonyl to produce the iron dihydride: 2 HCl + Na 2 Fe(CO) 4 → 2 NaCl + H 2 Fe(CO) 4
In the lab, phenyl-2-nitropropene is produced by the reaction of benzaldehyde and nitroethane in the presence of a basic catalyst like n-butylamine.The reaction is a nitroaldol reaction, and is a variant of a Knoevenagel condensation reaction, which is one of a broader class of reactions called Henry condensations, or simply Henry reactions.
The reaction produces fragments from the parent alkane, creating a diverse mixture of products; for instance, nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane are produced by treating propane with nitric acid in the gas phase (e.g. 350–450 °C and 8–12 atm).
Nitroethene can react at the 2π electron source in a [3+2] cycloaddition with nitrones. [5] [6] Nitroethylene is also reactive in domino-cycloaddition processes. For example, they can initially react with a chiral vinyl ether, and then react in a [3+2] cycloaddition with an electron deficient alkene such as dimethyl fumarate. The reactions are ...
Organic photochemistry encompasses organic reactions that are induced by the action of light. [ 1 ] [ 2 ] The absorption of ultraviolet light by organic molecules often leads to reactions. In the earliest days, sunlight was employed, while in more modern times ultraviolet lamps are employed.
Photosensitization is a process of transferring the energy of absorbed light. After absorption, the energy is transferred to the (chosen) reactants. This is part of the work of photochemistry in general. In particular this process is commonly employed where reactions require light sources of certain wavelengths that are not readily available. [14]
