Description

This diphenylphosphino-substituted oxazole integrates a reactive heterocyclic core with a versatile phosphine handle, enabling efficient coordination in transition metal catalysis. The dihydrooxazole ring provides structural rigidity and stability under standard conditions, while the para-phosphine moiety facilitates ligand assembly in palladium- and nickel-catalyzed cross-coupling reactions.

Application

2-[2-(Diphenylphosphino)phenyl]-4,5-dihydrooxazole serves as a versatile, bench-stable ligand precursor in palladium-catalyzed cross-coupling reactions. Its ortho-diphenylphosphinoaryl moiety enables efficient coordination to transition metals, facilitating C–C and C–heteroatom bond formations. The dihydrooxazole ring provides structural rigidity and enhances solubility, while the protected oxazole framework offers compatibility with diverse reaction conditions and simplifies purification.
