一般描述

4-溴甲苯是 对位取代的芳基溴。[1]在CuI/K2CO3/phen体系的催化下，4-溴甲苯可与2,4-二甲基苯酚发生C-O偶联反应。据报道，配合物[Cu（phen）（1-（2,4-二甲基苯氧基）-4-甲基苯]]+、 {H[Cu(phen)(2,4-dimethylphenoxy)]}+ 和[Cu(2,4-dimethylphenoxy)2]-可作为原位电喷雾电离质谱（ESI-MS）分析反应的中间体。[2]已有研究报道了使用乙酸钯（II）催化的4-溴甲苯与非荧光苯基硼酸（PBA）的Suzuki偶联反应。[1]已有研究描述了在微结构连续反应器中钯催化的4-溴甲苯与哌啶的C-N交叉偶联反应。[3]据报道，当存在原位生成的膦官能化N-杂环卡宾配体的钯配合物时，4-溴甲苯与苯乙烯会发生Heck反应。[4]

应用

4-溴甲苯可用于通过Cu/Pd催化的脱羧交叉偶联反应而合成酮。[5]

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.
      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

  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
