Applicazioni

4-Fluorophenylboronic acid can be used as a reactant in coupling reactions with arenediazonium tetrafluoroborates,[1] iodonium salts, and iodanes.[2] It is also used to make novel biologically active terphenyls.[3]

It can also be used as a reactant in:
  • Suzuki coupling using microwave and triton B catalyst.[4]
  • Pd-catalyzed direct arylation of pyrazoles with phenylboronic acids.[5]
  • Mizoroki-Heck and Suzuki-Miyaura coupling reactions catalyzed by palladium nanoparticles.[6]
  • Cu-catalyzed Petasis reactions.[7]
  • Tandem-type Pd(II)-catalyzed oxidative Heck reaction and intramolecular C-H amidation sequence.[8]
  • Ruthenium catalyzed direct arylation.[9]
  • Rh-catalyzed asymmetric conjugate additions.[10]
  • Ligand-free copper-catalyzed coupling of nitro arenes with arylboronic acids.[11]
  • Regioselective arylation and alkynylation by Suzuki-Miyaura and Sonogashira cross-coupling reactions.[12]
  • Suzuki cross-coupling of tetrabromothiophene.[13]
  • Palladium-catalyzed addition to nitriles.[14]

The chemoselective reaction of the C- followed by the O-centered naphthyl radicals with the more electron-deficient hypervalent bond of the diaryliodonium(III) salts is described. This discovered reactivity constitutes a new activation mode of the diaryliodonium(III) salts which enabled a one-pot

The palladium-catalyzed cross-coupling reaction of iodinanes (iodonium salts and iodanes) with organoboron compounds to form carbon-carbon bonds was achieved at ambient temperature under aqueous conditions in the absence of base.

Domande

1–2 di 2 domande  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 risposta

    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 risposta

    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
