Descripción general

Cu is present in +1 (cuprous) valence state in CuCl.[1] CuCl is a semiconductor having a wide band gap. It is a promising candidate for use in silicon-based optoelectronics since its lattice resembles with silicon. It participates in various reactions with Grignard reagents.[2]

Aplicación

Copper(I) chloride (Cuprous chloride, CuCl) has been used to synthesize 7-((tert-butyldimethylsilyl)oxy)hepta-2,4-diyn-1-ol.[3] CuCl may be used in the stereospecific synthesis of cyclic conjugated dienes.[4] It may be employed as a reactant to investigate the stability of copper chloride complexes in hydrothermal solutions.[1]
Shows unique character as an initiator of radical reactions such as the hydrostannation of α,β-unsaturated ketones.

A catalytic asymmetric Henry reaction has been developed with use of a sulfonyldiamine-CuCl complex as a catalyst. A series of new binaphthyl-containing sulfonyldiamine ligands (2a-h) were readily synthesized in two steps starting from commercially available chiral 1,2-diamines. The (R,R)-diamine-(R)-binaphthyl ligand

Promoted by CuCl/CCl(4), a variety of sulfonyl azides and tertiary amines were successfully coupled to give sulfonyl amidine derivatives in good to excellent yields. A possible mechanism for this reaction is discussed.

Questions

1–2 of 2 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
