prepared as an effective nanomicelle-forming species for general use in metal-catalyzed cross-coupling reactions in water. Several “name” reactions, including Heck, Suzuki−Miyaura, Sonogashira, and Negishi-like couplings, have been studied using this technology, as have aminations, C−H activations, and olefin metathesis reactions. Physical data in the form of DLS and cryo-TEM measurements suggest that
一种环境友好的表面活性剂 (TPGS-750-M),一种由外消旋 α-生育酚、MPEG-750 和琥珀酸组成的二酯,已被设计并易于制备为一种有效的纳米胶束形成物质,通常用于金属催化交叉- 水中的偶联反应。已经使用该技术研究了几种“名称”反应,包括 Heck、Suzuki-Miyaura、Sonogashira 和 Negishi-like 偶联,以及胺化、CH 活化和烯烃复分解反应。DLS 和冷冻 TEM 测量形式的物理数据表明,颗粒大小和形状是实现高水平转化的关键因素,因此,产品的分离产率很高。这种新的两亲物将很快上市。
