I-Burgess Reagent CAS 29684 - 56 - 8

Burgess reagent CAS 29684-56-8

Incazelo emfushane:

Igama lamakhemikhali:I-Burgess reagent
Elinye igama:(Methoxycarbonylsulfamoyl) Triethylammonium hydroxide, usawoti wangaphakathi; Methyl n - (triethylamnonisulfonl) carbamate
Cas Cha:Ngo-29684 - 56 - 8
Ukumsulwa:I-95% min (HPLC)
Ifomula:Ch3o2cnso2n (C2H5) 3
Isisindo samangqamuzana:238.30
Izakhiwo zamakhemikhali:I-Burgess Recegent, i-methyl n - (Triethylamniumsulfonyl) Carbamate, usawoti wangaphakathi wama-carbamates asetshenziswa njenge-ejenti yokuphelelwa ngamandla ku-organic chemicry. Kumhlophe okuphuzi okuphuzi okuphuzi, okuncibilikayo ezinhlafunweni eziningi ze-organic. Isetshenziswa kakhulu ekuphenduleni kokuqedwa kwe-CIS nokuphelelwa ngamandla komzimba wesibili nokwakheka kwamabanga aphakeme ukwakha ama-alkene, futhi ukusabela kuwumnene futhi kukhetha. Kepha umphumela wokusabela ngotshwala oyinhloko awumuhle.

    Isicelo

    I-ejenti ye-burgess deshydrating, ebizwa nangokuthi i-burgess reagent, yi-methyl n - (Triethyyisaminosullfurl) carbamate. Ingakhubazeka ngaphansi kwezimo ezimnene futhi i-ejenti yokukhetha ngokweqile ekhethiwe. Isetshenziselwa ukuguqula utshwala obusekokweni nobuthuthukile ngama-protons aseduze kuya ku-Alkene.

    Ingalungiswa ngokusabela kwe-chlorulfone isocyanate ne-triethylamine e-methanol. Ngesikhathi sokuphelelwa komzimba, isibabule sihlaselwa yi-hydroxyl Group, bese kuqedwa ukuqedwa kwe-CIS. Ama-ejenti we-burgess deshydrating angasetshenziswa futhi ukuhlanganisa amakhompiyutha e-isonitrile kusuka eForamide. Indlela yokuphendula iyafana nokusabela kokususwa kwe-Xanthate, kanti i-Alkene nayo itholwa ngokuqedwa kwe-CIS yesimo senguquko kwabayisithupha - Indandatho yeLungu.

    I-100g / 500g / 1kg / 25kg noma njengesicelo;
    Okungenzi kube amakhemikhali anobungozi, ukugcinwa okucacile kumazinga okushisa aphansi (2 - 8 ° C).
    (Ukufakwa okukhethekile, akukho ukwenziwa kabusha. Ayikho i-Crygenic Transport iyadingeka.)
