General description

Trimethyltin chloride is an organotin reagent widely used in transferring trimethylstannyl groups onto the substrates to synthesize various organostannanes. Trimethylstannyl compounds derived from this reagent, are extensively used in the palladium-catalyzed Stille coupling reactions.

Application

Trimethyltin chloride can be used as a precursor to synthesize trimethyltin hydride, cyanide, methoxide, azide, and lithium compounds.[1]
It can also be used as a reagent to prepare:
  • Organotrimethyltin derivatives by reacting with organocopper compounds via transmetalation reaction.[1]
  • Acetophenone by palladium-catalyzed coupling reaction with benzoyl chloride.[1]
  • Optically active propargyl trimethylstannane by treating with chiral allenyltitanium.[1]
  • Trimethylstannyl nucleophiles, which are applicable in the formation of Sn-C bonds via SN2 reactions, SRN1 reactions, and halogen-metal exchanges.[1]
  • Carbocycles by reacting with unactivated dienes or trienes via radical-mediated carbocyclization reaction in the presence of NaBH3CN and a catalytic amount of AIBN.[1]

Me3SnCl can also be used as a Lewis acid catalyst in asymmetric allylic alkylation reactions.[1]

Questions

1–2 of 2 Questions  

  1. 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

  2. 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.
