    A Rh(II)-catalyzed formal [3+3] cyclization of diazonaphthoquinones and propargyl alcohol is reported to afford 2,3-dihydro-1,4-benzodioxins. Various terminal propargyl alcohols react with diazonapthoquinone in the presence of Rh2(OAc)4 to give the corresponding dihydrodioxins in good to high yields. However, dihydrodioxins are not formed in the reaction of internal propargyl alcohols, and the O–H

  • Personal care compositions with color changing indicator

    The invention describes a composition for use in disinfecting a surface for personal use, such as a public restroom facility or telephone. The composition and delivery of the composition provides for the placement of a thin layer of disinfectant which includes a acid-base indicator. The acid-base indicator disappears as the thin layer effects the germicidal activity of the disinfectant. The composition is also rapidly drying, so that the acid-base indicator disappears as well as the disinfecting composition leaving the surface dry. The invention also relates to use of the compositions in a lotion, such as a sunscreen. Use of the acid-base indicator provides a method to visualize where the lotion is applied by color, with the color then later dissipating.
    本发明描述了一种用于消毒个人使用表面的组合物,例如公共洗手间或电话。该组合物及其输送方式提供了一层薄薄的消毒剂,其中包括酸碱指示剂。随着薄层发挥消毒剂的杀菌活性,酸碱指示剂消失。该组合物也具有快速干燥的特性,因此酸碱指示剂以及消毒剂在表面干燥后也会消失。本发明还涉及将该组合物用于洗涤剂,例如防晒霜。使用酸碱指示剂提供了一种通过颜色可视化涂抹洗涤剂的方法,颜色随后会消失。
