General description

Bis(triphenylphosphine)palladium(II) dichloride ((PdCl2(PPh3)2) is an organopalladium complex containing tertiary phosphine ligands that is commonly used in C-C bond forming reactions such as Heck arylation, Suzuki coupling, Stille coupling, and Sonogashira coupling.[1]

Application

Bis(triphenylphosphine)palladium(II) dichloride can be used as a catalyst in the:
  • Coupling of 2-iodoanisole and terminal alkynes to synthesize 2,3-disubstituted benzofurans.[2]
  • Copper-free Sonogashira cross-coupling reaction to synthesize diphenylacetylene.[3]
  • Regioselective hydrocarboxylation of styrene.[4]
  • Negishi coupling of fluoroarylzinc pivalates to prepare fluorinated oligophenyls.[5]
  • Coupling of iodo-α-β-unsaturated esters to afford tetrasubstituted olefins.[6]
For small scale and high throughput uses, product is also available as ChemBeads (927759)

The efficient regioselective and stereospecific synthesis of tetrasubstituted olefins using a mild and convenient method is disclosed. 2-Alkynyl esters are selectively converted to E-beta-chloro-alpha-iodo-alpha,beta-unsaturated esters by exposure to Bu4NI in refluxing dichloroethane. These products are produced cleanly, regio- and stereoselectively

Questions

1–5 of 5 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.

  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
