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

Palladium catalyzed phosphination of substituted aryl bromides
using triarylphosphines as the phosphinating agents has been developed;
this method tolerates ketone, aldehyde, ester, nitrile, ether and chloride
functional groups.
The synthesis of three triphenylphosphineanalogues with phenyl groups replaced by (4-tert-butyl)phenyl and (3-sulfonato)phenyl group is described. The surface-active properties of these new compounds are reported. The catalytic activities obtained with these phosphines in the palladium-catalyzed cleavage of undecyl allyl carbonate were up to 24000 times higher than those observed with trisulfonated
The palladiumcatalysed Pd-aryl/P-aryl exchange was applied in the synthesis of various functionalised phosphines from their corresponding substituted aryl triflates using triarylphosphines as the phosphinating agents. This method tolerated many functional groups including ketone, aldehyde, ester, nitrile, methyl ether, pyridyl and chloride groups.
