  钯催化未激活的C（sp 3）–H键的位点选择性氟化

  摘要：

  过渡金属催化的直接C–H键氟化是制备有机氟的有吸引力的合成工具。尽管存在许多直接进行sp 3 C–H官能化的方法，但未活化的sp 3碳的位点选择性氟化仍然是一个挑战。据报道，通过钯催化的双齿配体定向的C–H键官能化过程，可以在未活化的sp 3碳上进行直接，高度位点选择性和非对映选择性的氟化。用这种方法，以乙酸钯为催化剂，Selectfluor为氟源，制备了多种在医学和农业化学中重要的基序的β-氟化氨基酸衍生物和脂族酰胺。

  A construct that comprises a base material and a polyhydroxyalkanoate, wherein at least a part of the base material is coated with the polyhydroxyalkanoate, and the polyhydroxyalkanoate comprises a 3-hydroxyalkanoic acid unit other than 3-hydroxypropionic acid unit, 3-hydroxy-n-butyric acid unit, and 3-hydroxy-n-valeric acid unit. In addition, an electrostatic charge image developing toner allows to design the toner characteristics such as chargeability, flowability, stability in time and environmental stability uniform among the toners of different colors. The toner has a small particle size enough for enabling uniform dispersion and being excellent in color saturation and transparency. The toner also shows higher contribution to the environmental security. The toner includes a coloring agent of which at least a part of the surface is covered with polyhydroxyalkanoate (PHA). The toner is produced by dispersing the coloring agent in aqueous medium, then fixing PHA synthesizing enzyme to the coloring agent dispersed in the aqueous medium, then adding 3-hydroxyacyl CoA, and executing a PHA synthesizing reaction to cover at least a part of the surface of the coloring agent with PHA. The toner thus obtained is used for an image forming method.
