Application

1,2-Bis(dicyclohexylphosphino)ethane can be used as a ligand for:
  • Pd-catalyzed decarbonylative C-H coupling of azoles and aromatic esters.[1]
  • Ni-catalyzed cross-coupling reaction of aryl fluorides and primary amines.[2]

Reactant involved in:
  • Investigations of the role of ligand-based steric effects during the polymerization
  • Synthesis of molybdenum nitrosyl complexes for use as Imine hydrogenation catalysts
  • Irreversible thermal linkage isomerization of switchable C-N-bound isomers
  • Chelating for conversion of trans complexes to cis complexes

Precursor for Iridium trisboryl complexes and the substituent effect on borylation reactions

Ligand for palladium(II) complex catalyzed hydrogenation reactions

This manuscript details the development of the nickel-catalyzed arylation of oxazoles and benzoxazoles with aryl halides. A series of aryl, heteroaryl, and druglike electrophiles relevant to pharmaceutical applications were surveyed. The desired arylated products were obtained in synthetically useful yields

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.
