Product Overview

4-(Diphenylamino)phenylboronic acid (CAS 201802-67-7) is a functionalized triphenylamine boronic acid derivative with the molecular formula C₁₈H₁₆BNO₂ and a molecular weight of 289.14 g/mol. The compound features a triphenylamine core with a boronic acid group at the para position. This compound is a key building block for the synthesis of organic semiconductors, hole-transporting materials, and functional materials via Suzuki-Miyaura cross-coupling reactions. It is a white to off-white crystalline powder with good stability under proper storage conditions.

Synthetic Process

The synthesis typically involves the lithiation of 4-bromotriphenylamine followed by reaction with triisopropyl borate or trimethyl borate, then hydrolysis to yield the boronic acid. Alternatively, it can be synthesized via palladium-catalyzed borylation of 4-bromotriphenylamine with bis(pinacolato)diboron (B₂pin₂) followed by deprotection.

Mechanism of Action

The boronic acid group enables Suzuki-Miyaura cross-coupling reactions with various aryl or heteroaryl halides, allowing the introduction of triphenylamine moieties into complex molecular architectures. The triphenylamine core exhibits excellent hole-transporting properties.
