Application

4-Aminophenylboronic acid pinacol ester can be used as a reagent for:
  • The preparation of substituted 3-phenyl-4H-1-benzopyran-4-ones by reacting with iodochromones via Pd catalyzed Suzuki-Miyaura cross-coupling reaction.
  • Mercury(II) detection by fluorometry with new fluorogenic indicators based on through-bond energy transfer from pentaquinone to rhodamine.
  • Rhodium-catalyzed amination reactions.
  • Palladium-catalyzed Suzuki cross-coupling to synthesize potential antitubercular and antimicrobial compounds.

It can also be used to prepare:
  • Hexaphenylbenzene derivatives as a potential bioprobe and multichannel keypad system.
  • Pyromellitic diimide-based polymer as matrix for solution-processable n-channel field-effect transistors.
  • Alternating copolymers of oligoarylenes and naphthalene bisimides as low band-gap semiconductors with electrochemical and spectroelectrochemical behavior.
  • γ-secretase modulators in the treatment of amyloid β formation.

A new series of fluoro-, methoxyl-, and amino-substituted isoflavones have been synthesized as potential antitumor agents based on structural similarities to known flavones and isoflavones (quercetin and genistein respectively) and antitumor 2-phenylbenzothiazoles. Target compounds were synthesized using palladium-catalyzed coupling methodologies
