Description and Uses

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.
