General description
特伯试剂是一种由有机金属化合物进行稳定化的路易斯酸，其用于将羰基转化为β-取代亚甲基。它也可与多种羰基化合物（包括酯、酰胺和内酯）反应生成相应的烯烃。
Application
特伯试剂可用于：
- 使叶绿素衍生物的羰基转化为相应的环外亚甲基（亚乙烯基）。
- 参与由3-OH乙二醇酯合成β-C糖苷的反应。
- 作为多功能的亚甲基试剂参与酮和醛转化为烯烃的反应。它可与受阻酮进行温和的反应，并可使酯转化为乙烯基醚。
- 使醛烯化。
- 使具有高非对映选择性的手性多羟基酮亚甲基化。
Packaging
建议将25 mL Sure/Seal™ 瓶作为一次性瓶使用。 反复穿刺可能导致产品性能下降。
