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 C–P(III) bond formation reaction employing acylphosphines as the phosphorus source was developed. Under the optimized conditions, acylphosphines could react with aryl halides directly affording trivalent phosphines in up to 94% yield.
Nickel-catalysed electrochemical cross-coupling between aryl- or heteroaryl-halides and chlorodiphenylphosphine or dichlorophenylphosphine affords tertiary phosphines in good to high yields.

halides with diaryl and dialkyl phosphines, as well as with dibutyl phosphite, is reported. This highly efficient transformation is realized through the use of copper(I) iodide as a catalyst, N,N'-dimethylethylenediamine as a ligand, and Cs(2)CO(3) as a base. A variety of sterically hindered and/or functionalized substrates were found to react under these reactionconditions to provide products in good
