:p-Tolilmagnésio brometo
Descrição:
p-Tolilmagnésio brometo, com o número CAS 4294-57-9, é um composto organomagnésico classificado como um reagente de Grignard. É caracterizado pela presença de um grupo p-tolila (um grupo fenila substituído por um metila) ligado a um átomo de magnésio, que está associado a um íon brometo. Este composto geralmente aparece como uma solução incolor a amarelo claro quando dissolvido em éter ou outros solventes adequados. p-Tolilmagnésio brometo é altamente reativo, particularmente com água e solventes próticos, levando à liberação de hidrocarbonetos e à formação de hidróxido de magnésio. É comumente utilizado na síntese orgânica para reações de adição nucleofílica, permitindo a formação de ligações carbono-carbono. A reatividade deste reagente de Grignard o torna valioso na preparação de vários compostos orgânicos, incluindo álcoois e outras moléculas funcionalizadas. Devido à sua reatividade, deve ser manuseado em condições anidras para evitar decomposição e garantir reações bem-sucedidas.

CAS:Produto Controlado<p>p-Tolylmagnesium Bromide is a Grignard reagent that is used in organic synthesis. It can be used to synthesize new compounds and is an important reagent in the palladium-catalyzed cross-coupling reaction. In this reaction, the Grignard reagent reacts with a halide to form an organometallic intermediate. The nucleophile (typically an alcohol) then attacks the carbon atom of the organometallic intermediate, displacing one of its bromine atoms and forming a new carbon-carbon bond. The magnesium can also be replaced by other metals such as zinc or lithium. p-Tolylmagnesium Bromide is often used as a catalyst for cationic polymerization reactions. It is also used to remove chlorine from chlorides, fluorine from fluoroalkanes, sulfides from sulfoxides, and tosylates from tosylate esters. p-Tolylmagnesium Bromide has</p>Fórmula:C7H7BrMgPureza:Min. 95%Peso molecular:195.34 g/mol
