Arylboron compounds with electron-withdrawing aromatic groups such as triarylborons, diarylborinic acids, and arylboronic acids represent a new class of air-stable and water-tolerant Lewis acid or Bronsted acid catalysts in organic synthesis. In particular, arylboronic acids are showing to be powerful tools in the design of chiral boron catalysts. [Pg.108]

Diarylborinic acids and arylboronic acids bearing electron-withdrawing substituents are useful as air-stable Lewis acid catalysts for various organic transformations. In particular, the potential of 3,5-(CF3)2C6H3B(OH)2 as a Lewis acid catalyst has strikingly increased since Yamamoto and Ishihara s initial study [32b]. Continued exploratory research on the application of arylboron compounds as air-stable and reusable catalysts is expected to provide powerful and practical methods for various Bronsted-Lewis acid-catalyzed organic transformations.
