  用氟化银（I）对硫代苯并二恶唑进行氟硫磺化。

  摘要：

  二氟苯并二恶唑是在药物和农用化学品中都发现的重要官能团。HF和强氧化剂的典型氟化条件挑战了该官能团的后期引入。在这里，我们证明了可以从儿茶酚中分两步制备一系列二氟苯并二恶唑，方法是将其转化为硫代苯并二恶唑，然后用氟化银（I）进行脱硫氟化。这些温和的反应条件可与多种官能团兼容，并能够使用一系列官能化的二氟苯并二恶唑。

  [Problems] Provided are a highly marketable reversibly thermochromic composition that provides a black color during color development by using a fluoran derivative having a specific structure as an electron-donating color-developing organic compound, turns colorless during decoloration, and is excellent in contrast between a colored state and a decolored state and a microcapsule pigment encapsulating the same. [Solution] Disclosed are a reversibly thermochromic composition including: (a) a fluoran derivative having a specific structure as an electron-donating color-developing organic compound; (b) an electron-accepting compound; and (c) a reaction medium which reversibly induces an electron transfer reaction between the component (a) and the component (b) in a specific temperature range, and a reversibly thermochromic microcapsule pigment encapsulating the same.

  Provided are a reversibly thermochromic aqueous ink composition having excellent writability and few problems such as aggregation of a colorant, an increase in viscosity of the composition, or a decrease in handwriting density, and a refill or an aqueous ballpoint pen using the reversibly thermochromic aqueous ink composition. A reversibly thermochromic composition is a reversibly thermochromic aqueous ink composition containing a reversibly thermochromic microcapsule pigment encapsulated in a microcapsule formed from an organic resin, an N-vinyl-2-pyrrolidone polymer, glycerin, and water, in which when contents (% by mass) of the reversibly thermochromic microcapsule pigment, the N-vinyl-2-pyrrolidone polymer, and the glycerin with respect to a total mass of the ink composition are PMC, PPVP, and PG, respectively, 0.3 ≤ PMC/(PPVP + PG) ≤ 4, and 0.2 ≤ PPVP/PG ^ 5, and a refill or an aqueous ballpoint pen incorporating the reversibly thermochromic aqueous ink composition.
