Isopropylmagnesium Bromide Tshuaj Rau Tshuaj Raw Khoom CAS 920-39-8

Khoom Description

Isopropylmagnesium bromide tov rau Tshuaj Raw Khoom CAS 920-39-8 yog dab tsi?

Isopropylmagnesium Bromide (CAS 920-39-8) yog ib qho organomagnesium compound tseem hu ua bromo (isopropyl) magnesium thiab magnesium, bromo (1-methylethyl)-. Nrog rau cov mis molecular ntawm C₃H₇BrMg thiab molecular hnyav ntawm 147.3, nws belongs rau alkyl Grignard reagent chav kawm. Cov tshuaj no feem ntau tshwm sim raws li cov xim grey tsaus rau xim av xim pob tshab hauv cov kuab tshuaj xws li tetrahydrofuran (THF) lossis 2-methyltetrahydrofuran (2-MeTHF).
Isopropylmagnesium Bromide muaj qhov ceev ntawm 0.982 g / mL (25 degree, THF tov), ​​lub teeb nyem ntawm -17 degree, thiab melting point ntawm 114-116℃(dawb daim ntawv). Nws yog soluble hauv aprotic cov kuab tshuaj xws li THF thiab diethyl ether tab sis insoluble hauv hydrocarbons. Kev sib cuag nrog dej los yog dej cawv ua rau muaj kev kub ntxhov, tso cov pa hluav taws xob (xws li, propane) thiab tsim magnesium hydroxide.

Siv

Raws li ib tug nucleophilic reagent, Isopropylmagnesium Bromide koom nyob rau hauv peb yam tseem ceeb cov tshuaj tiv thaiv:
Carbonyl Ntxiv: Reacts nrog aldehydes, ketones, thiab esters los tsim isopropyl alcohols (xws li, tsim 2,3-dimethyl-2-butanol nrog acetone).
Hlau-Catalyzed Coupling: Ua rau palladium/nickel-catalyzed cross-coupling nrog halogenated hydrocarbons los qhia cov pab pawg isopropyl, txhawb kev sib txuas ntawm cov tshuaj intermediates lossis complex hydrocarbons.
Asymmetric Ketone Tsim: Reacts nrog acyl chlorides (xws li benzoyl chloride) los tsim asymmetric ketones zoo li benzophenone derivatives.

Cov ntaub ntawv kev nyab xeeb

Kev phom sij:
Nws yog flammable thaum ntub dej (H260), corrosive heev (H314), thiab tuaj yeem ua rau tawv nqaij kub hnyiab thiab qhov muag puas.
Vapor ua rau lub ntsws ua pa (H335), thiab muaj teeb meem yog tias nqus tau los yog noj (H302 / H332).
Kev ua haujlwm specifications:
Siv cov kuab tshuaj anhydrous nyob rau hauv inert gas tiv thaiv, tsis txhob muaj hluav taws xob zoo li qub thiab qhib nplaim taws.
Hnav cov hnab looj tes tiv thaiv, tsom iav thiab cov khaub ncaws tiv thaiv, thiab huv si huv si tom qab ua haujlwm.
Cia tej yam kev mob: Khaws nyob rau hauv ib qho chaw txias thiab qhuav tom qab sealing, kom deb ntawm oxidants thiab acidic tshuaj, thiab tsis txhob ntev - raug rau huab cua.
