一般描述

在CO气氛下氯化铂(II) (PdCl2) 与未取代或烷基取代的环酮反应,生成无环二酯和无环氯取代单酯。[1]在甲醇中PdCl2N,N-二甲基烯丙基胺反应生成二-μ-氯-二(2-甲氧基-3-N,N-二甲基氨基丙基二铂(II)。[2]在 [bmim][BF4]或[bmim][PF6] (其中[bmim]+ = 1-丁基-3-甲基咪唑阳离子) 离子液中,二氯化钯乙酸盐和乙酰丙酮化物已用于丁二烯的氢化二聚作用以形成2,7-辛二烯-1-醇。[3]

氯化铂(II) 可用作[4]Suzuki-Miyaura[5]和Mizoroki-Heck反应的氧化剂和催化剂。[6]

应用

钯催化交叉偶联反应的应用指南

用于合成含半导体金属的聚合物,其中聚吡咯骨架具有最小构象能并且几乎是平面的。
氯化钯(PdCl2)的研究用途:
  • 作为催化剂用于有机碲化物和一氧化碳的羰基化反应。[7]
  • 与Cu(II)一起作为催化剂,用于苯乙胺生成苯取代吡咯的脱胺反应。[8]
  • 与PEG 300一起,促进芳基氯化物和芳基硼酸进行高效的Suzuki偶联反应。[9]
对于小规模和高通量应用,可选用搭配XPhos配体的ChemBeads形式(919853)

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
