Poly(4-diphenylphosphinostyrene) (1), poly(4-dicyclohexylphosphinostyrene) (2), and poly (3) were obtained by polymerization of the corresponding monomers.The polymers were treated with (RhClL2)2 and with (RhClL')2, where L and L' are ethene and 1,5-cyclooctadiene, respectively.These complexes were added stepwise and during this process the 31P NMR spectra were observed. 31P chemical shifts and 103Rh-31P coupling constants were compared with those of monomeric analogues which were treated in the same way.
Palladium-Catalyzed C-P(III) Bond Formation by Coupling ArBr/ArOTf with Acylphosphines
Chen, Xingyu,Wu, Hongyu,Yu, Rongrong,Zhu, Hong,Wang, Zhiqian

Palladium-catalyzed C-P bond formation reaction of ArBr/ArOTf using acylphosphines as differential phosphination reagents is reported. The acylphosphines show practicable reactivity with ArBr and ArOTf as the phosphination reagents, though they are inert to the air and moisture. The reaction affords trivalent phosphines directly in good yields with a broad substrate scope and functional group tolerance. This reaction discloses the acylphosphines' capability as new phosphorus sources for the direct synthesis of trivalent phosphines.
Preparation of Aryl(dicyclohexyl)phosphines by C-P Bond-Forming Cross-Coupling in Water Catalyzed by an Amphiphilic-Resin-Supported Palladium Complex

Aryl(dicyclohexyl)phosphines were prepared by a catalytic C-P bond-forming cross-coupling reaction of haloarenes with dicyclohexylphosphine under heterogeneous conditions in water containing an immobilized palladium complex coordinated to an amphiphilic polystyrene-poly(ethylene glycol) resin supported di(tert -butyl)phosphine ligand.
