产品详细信息

详细说明 (English)

Application
Catalyst used in a ring opening of meso-aziridines with trimethylsilyl azide.5
In many asymmetric catalysis applications, glove box and Schlenk techniques should be employed to prevent exposure of the rare earth catalyst to air and moisture, which can be detrimental to the reaction outcome. Solutions of the catalyst should be made using anhydrous solvents and used shortly after preparation.
Catalyst for:
• Enantioselective construction of beta-quaternary carbons via conjugate addition reactions1
• Generation of reactive enolates2
• Regioselective / stereoselective conjugate addition of cyanide to enones3
• Strecker reactions4
• Asymmetric ring-opening of meso-aziridines5
Packaging
3 g in ampule
500 mg in ampule

Application
在很多不对称催化应用中，应当使用手套箱和 Schlenk 技术防止此稀土催化剂与空气和水分接触，因为这两个因素将对反应结果产生不利影响。用无水溶剂配制该催化剂溶液并立即使用。
用三甲基硅叠氮使内消旋-氮杂环丙烷开环的催化剂。5
