Diverse C-P Cross-Couplings of Arylsulfonium Salts with Diarylphosphines via Selective C-S Bond Cleavage

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. The use of a palladacycle catalyst under otherwise the same conditions enables the phosphination via the cleavage of an exocyclic C-S bond with significantly higher speed.

Pd-catalyzed P-C cross-coupling reactions for versatile triarylphosphine synthesis

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.

Radical phosphination of organic halides and alkyl imidazole-1- carbothioates

Taking advantage of a radical-based methodology, mild and chemoselective phosphination reactions of organic halide and alkyl imidazole-1-carbothioates have been developed. The mild reaction conditions allow labile functional groups to survive during the reaction. Copyright

ARYLIERUNG VON THIOPHOSPHORCHLORIDEN IN GEGENWART VON ALUMINIUM CHLORID

Differently substituted tertiary phosphine-sulfides are prepared in an one-pot-synthesis by reaction of PCl3 with benzene and sulfur via the intermediate phenylthiophosphonic-dichloride or by arylation of PSCl3 or organothiophosphonic-dichlorides via the isolable intermediates diorganothiophosphinic-chlorides.AlCl3 is used as catalyst.
