Pd-Catalyzed P–C Cross-Coupling Reactions for Versatile Triarylphosphine Synthesis
摘要:
Practical and versatile syntheses of tertiary phosphine derivatives have been achieved by palladium-catalyzed deformylative P-C cross-coupling reactions of hydroxymethylphosphine derivatives. Sequential couplings of orthogonally protected precursors provide a simple and practical route toward a variety of tertiary phosphine derivatives having aryl substituents in any combination.

Diverse C–P cross-couplings of arylthianthrenium salts with diarylphosphines producing various triarylphosphines via highly selective C–S bond cleavage are reported. In the absence of catalyst, the reaction of arylthianthrenium salts with diarylphosphines undergoes phosphinative ring opening exclusively via the cleavage of an endocyclic C–S bond of a thianthrene skeleton.

A powerful method for versatile phosphine synthesis: The P–C coupling of hydroxymethylphosphine sulfide derivatives with various aryl bromides and triflates to yield triarylphosphine sulfides has been developed. The new method was successfully applied to the sequential triple coupling of an orthogonally protected precursor to give an unsymmetrically substituted triarylphosphine sulfide.
