Application

Copper(I) iodide can be used as a catalyst for:
  • For arylation of pyrazole and derivatives by coupling arenediazonium species under mild and ligand-free conditions.
  • Selective cross-coupling of dibromo alkenes and heteronucleophiles which leads to numerous building blocks such as 1-bromoenamides, ynamides, ketene N, N-acetals, 1-bromoenol ethers, ynol ethers, ketene O, O-acetals, and vinyl phosphonates.
  • Stereospecific and the regioselective reaction of silacyclopropanes with carbonyl compounds.
It can also be used as a starting material in the preparation of diphenylphosphinepyridine-derivatives (PyrPHOS)-copper iodide complexes which are suitable for use in OLEDs.

Features and Benefits

  • Low toxicity
  • Mild reaction condition
  • High purity ensures reproducibility and avoids cocatalysis by contaminants.

White light-emitting diodes (WLEDs) are promising next-generation solid-state light sources. However, the commercialization route for WLED production suffers from challenges in terms of insufficient color-rendering index (CRI), color instability, and incorporation of rare-earth elements. Herein, a new two-component strategy is

A domino synthesis of 5,12-dihydroindolo[2,1-b]quinazoline derivatives via copper-catalyzed Ullmann-type intermolecular C-C and intramolecular C-N couplings is reported. Good yields of various 5,12-dihydroindolo[2,1-b]quinazoline derivatives were obtained. Reaction scopes, limitations, and the reaction mechanism are discussed.

Questions

1–6 of 6 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.
      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

  5. If the purity of 99.999% for Product 215554, Copper (I) Iodide is based solely on trace metal content, then what is the chemical purity of this product?

    1 answer

    1. We do not report a chemical purity for this product, however, an approximation of the purity can be determined by taking the value for the Copper content reported on the Certificate of Analysis and dividing it by the theoretical content of 33.4%.  (It is a an approximation because there could be other Copper containing impurities present that may contribute to the value).

  6. Product 215554, Copper (I) Iodide has turned grayish in color.  Is it still good?

    1 answer

    1. This compound is light sensitive.  It is cream colored when first it is first produced, then slowly turns grayish in color because of its photosensitivity.  Chemical purity is not significantly compromised by modest homogeneous appearance changes.
