| | マロン酸エチルカリウム Usage And Synthesis |
| 外観 | 白色〜ほとんど白色, 結晶〜結晶性粉末又は塊 | | 溶解性 | 水及びエタノールに溶け、アセトンにほとんど溶けない。 | | 使用上の注意 | アルゴン封入 | | 化学的特性 | white crystals or powder | | 使用 | Ethyl potassium malonate (potassium ethyl malonate) may be used to generate (trimethylsilyl)ethyl malonate in situ, which can be acylated to prepare a variety of β-ketoesters or alkylidene malonates. | | 使用 | Ethyl potassium malonate is used as a competitive inhibitor of the enzyme succinate dehydrogenase. It acts as a precursor to produce (trimethylsilyl)ethyl malonate, which is utilized to prepare beta-ketoesters by acylation. Further, it reacts with aryl nitriles to prepare beta-amino acrylates in the presence of zinc chloride and a catalytic amount of Hünig's base. In addition to this, it serves as an intermediate for the preparation of ethyl tert-butyl malonate. | | 一般的な説明 | Ethyl potassium malonate (potassium ethyl malonate) reacts with aryl nitriles in the presence of zinc chloride and a catalytic amount of Hünig′s base to yield β-amino acrylates. Ethyl potassium malonate is formed as an intermediate during the synthesis of ethyl tert-butyl malonate. |
