应用

三氟甲磺酸三甲基硅酯可与三氟化硼醚合物一起使用，用于在手性配体存在的情况下，进行有机锂试剂与烯丙基溴化物、氯化物和醚的铜催化不对称烯丙基烷基化 (AAA)。[1][2]
可用于：
  • 作为硅烷化试剂， 用于以α-重氮基乙酰乙酸酯合成三甲基硅烯醚。[3]
  • 活化苄基醚和烯丙基醚，进行硫化物的烷基化。[4]
  • 在不形成甲氧基酮副产物的情况下，促进Danishefsky′二烯的 Diels-Alder 加合物转化为环己烯酮。[5]
  • 制备二氟硼酸三氟甲磺酸酯醚合物，其是一种强路易斯酸，在乙腈溶剂中尤其如此。[6]
  • 作为酯-酰亚胺和二酯的迪克曼环化反应试剂。[7]

它还可用于催化：
  • 醇与酸酐的酰化[8]
  • 羰基化合物与三烷基硅烷的还原偶联以形成对称醚。[9]
  • 4-脱甲氧基道诺霉素酮与1-O-酰基-L-道诺糖胺衍生物的糖苷化。[10]

Questions

1–2 of 2 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
