Descrizione generale

Di-n-butylmagnesium solution is a useful reagent for the synthesis of organomagnesium compounds.

Applicazioni

Di-n-butylmagnesium solution can be used as a reagent for the deprotection of aromatic and aliphatic benzyl thioethers to synthesize corresponding benzylthiols in the presence of titanocene dichloride[1]. It can also be used as a catalyst to synthesize enantioenriched nitrogen-containing heterocyclic derivatives by the asymmetric ring-opening reaction of aziridines with substituted tetrazoles in the presence of chiral ligand[2].

A magnesium-catalyzed asymmetric ring-opening reaction of aziridines with substituted tetrazoles is reported. The current protocol proceeds smoothly and gives the corresponding desymmetrization products in high yields and good enantioselectivities.

Domande

1–2 di 2 domande  

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

    1 risposta

    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 risposta

    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

    Terrible product - consistently contaminated with THF

    Contains THF, should be advertised as Mg(nBu)2(THF)2 for clarity.
