In chemistry, a reactive intermediate or an intermediate is a short-lived, high-energy, highly reactive molecule. When generated in a chemical reaction, it will quickly convert into a more stable molecule.
In chemistry, a reactive intermediate or an intermediate is a short-lived, high-energy, highly reactive molecule. Only in exceptional cases can these compounds be isolated and stored, . low temperatures, matrix isolation. When their existence is indicated, reactive intermediates can help explain how a chemical reaction takes place.
As these intermediates are highly reactive, they cannot . NITRENES Introduction Structure and Reactivity Generation of Nitrenes Reactions of Nitrenes Summary.
As these intermediates are highly reactive, they cannot usually be isolated, but their existence and structure can be proved by theoretical and experimental methods. Most reactions in organic chemistry do not proceed in a single step but rather take several steps to yield the desired product.

In chemistry, a nitrene or imene (R–N) is the nitrogen analogue of a carbene. The nitrogen atom is uncharged and univalent, so it has only 5 electrons in its valence level-one covalent bond and four non-bonded electrons
In chemistry, a nitrene or imene (R–N) is the nitrogen analogue of a carbene. The nitrogen atom is uncharged and univalent, so it has only 5 electrons in its valence level-one covalent bond and four non-bonded electrons. It is therefore considered an electrophile due to the unsatisfied octet. A nitrene is a reactive intermediate and is involved in many chemical reactions. The simplest nitrene, HN, is called imidogen, and that term is sometimes used as a synonym for the nitrene class.

Nitrene Intermediate : Introduction, Synthesis, Reactions Organic Chemistry. Because nitrenes are so reactive, they are not isolated. Instead, they are formed as reactive intermediates during a reaction. Nitrene and Benzyne -Reaction Intermediate GOC-24 CLASS XI CHEMISTRY. There are two common ways to generate nitrenes
Reactive intermediates such as nitrenes, carbenes, and . Azomethine ylides are reactive intermediates in organic chemistry. They are easily generated in situ from the condensation of α-aminoacids 5 with aldehydes 6 or ketones.
Reactive intermediates such as nitrenes, carbenes, and radicals have been used in cyclization reactions which produce aziridines and azirines. Intermolecular aziridination reactions with nitrenes were covered in Section . 1.
