General description

Phenylmagnesium bromide solution contains 3M phenylmagnesium bromide in diethyl ether. It can act as a strong acid and Lewis acid. It can undergo addition reaction with many unsaturated functional groups. The phenyl group can displace halide from other organic compounds.[1] Phenylmagnesium bromide is a Grignard reagent. Reaction of β-cyclohexanedione (dihydroresorcinol) with phenylmagnesium bromide has been investigated.[2]

Application

Phenylmagnesium bromide was used for the synthesis of end-functionalized regioregular poly(3-alkylthiophene)s.[3] It was also used for the monoalkylation of aliphatic primary amine to generate secondary amines by the Grignard reaction of 1-[(alkylamino) methyl] benzotriazoles.[4]
It may be used for synthesis of the following:
  • 1,3,3-trimethyl-6-phenyl-2-oxabicyclo[2.2.2]octan-6-ol[5]
  • 6-benzyl-1,3,3-trimethyl-2-oxabicyclo[2.2.2]octan-6-ol[5]
  • (3-(2-Dithiobenzoatepropionyl)propyl)dimethylmethoxysilane, reversible addition-fragmentation chain transfer polymerization (RAFT)-silane agent[6]
  • series of o-substituted benzophenones[7]

Other Notes

Storage below 25°C may cause formation of crystalline magnesium salts. Moving container to a warm location and occasional gentle swirling should redissolve the solid

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
