Synthesis of alkyl- and aryldiphenylphosphines via electrogenerated magnesium chloride diphenylphosphanide
Nechab, Malek,Le Gall, Erwan,Troupel, Michel,Nédélec, Jean-Yves
, p. 1809 - 1813 (2006)
A two-steps procedure allowing the formation of alkyldiphenylphosphines and aryldiphenylphosphines in good yield is described. It relies on the electrochemical preparation of magnesium chloride diphenylphosphanide and its subsequent coupling with either alkyl halides or aryl fluorides.

Poly(9,9-dioctylfluorene) (PFO) with Mn values above 100 000 g mol-1 in a toluene/water system and Mn values up to 600 000 g mol-1 in a THF/water system has been obtained by improved Suzuki polycondensation using a new kind of amphipathic palladium catalyst with self-phase-transfer features, which could overcome the disadvantage caused by the immiscible biphasic mixture and accelerate the transmetalation step (see figure).

Functionalized triaryl- and diarylalkylphosphines are accessible in high yields following a mild fluoride catalyzed phosphorous-carbon coupling protocol starting from fluoroarenes and silylated phosphines. The reaction requires a minimum of solvent and ca
Synthesis of symmetrical and unsymmetrical functionalized arylphosphines from chlorophosphines and organozinc reagents
Le Gall, Erwan,Ben A?ssi, Karima,Lachaise, Isabelle,Troupel, Michel
, p. 954 - 956 (2007/10/03)
A stepwise procedure allowing the formation of symmetrical arylphosphines is described. It relies on the use of preformed functionalized aromatic organozinc reagents to perform arylations of chlorophosphines. Some preliminary results concerning the synthesis of unsymmetrical diarylphenylphosphines through sequential coupling of organozinc species with dichlorophenylphosphine are also reported.

Synthesis of aryl phosphines via phosphination with triphenylphosphine by supported palladium catalysts
Wang, Yanchun,Lai, Chi Wai,Kwong, Fuk Yee,Jia, Wen,Chan, Kin Shing
, p. 9433 - 9439 (2007/10/03)
The palladium catalyzed phosphination of functionalized aryl bromides, triflates, and chlorides with triphenylphosphine to yield aryldiphenylphosphines was catalyzed by thermally stable palladium catalysts supported on charcoal and aluminia. The addition
Nickel-catalyzed reductive coupling of chlorodiphenylphosphine with aryl bromides into functionalized triarylphosphines
Le Gall, Erwan,Troupel, Michel,Nédélec, Jean-Yves
, p. 7497 - 7500 (2007/10/03)
Functionalized triarylphosphines are obtained with good yields in a one-step reaction of an equimolar mixture of chlorodiphenylphosphine and an aromatic bromide in NMP or DMF at 110°C in the presence of zinc dust and a catalytic amount of NiBr2
Electrosynthesis of triorganylphosphines from organic halides and chlorophosphines, catalyzed by nickel complexes
Budnikova,Kargin,Sinyashin
, p. 524 - 528 (2007/10/03)
The possibility of cross coupling of organic halides and chlorophosphines under the action of electrochemically generated Ni(0) complexes of 2,2′-bipy is shown. The final triorganylphosphines are formed by several pathways, including reaction of the σ complex of ArNiX with chlorophosphine and electron transfer-induced reductive elimination of Ph2PArNiX, leading to the cross-coupling product.
Nucleophilic phosphanylation of fluoroaromatic compounds with carboxyl, carboxymethyl, and aminomethyl functionalities - An efficient synthetic route to amphiphilic arylphosphanes
Hingst, Martin,Tepper, Michael,Stelzer, Othmar
, p. 73 - 82 (2007/10/03)
Chiral- and multiply-carboxylated phosphanes and phosphanyl derivatives of benzoic and phthalic acids (1-9) are accessible in high yields by nucleophilic phosphanylation of potassium or lithium salts of commercially available fluorobenzoic and 3-fluorophthalic acids with Ph2PH, Ph2PK, PhPLi2, Ph(K)P-(CH2)3-P(K)Ph in superbasic media (DMSO/KOH) or in THF and DME. The hitherto unknown phosphanylphenylacetic acids (10-13) and phosphanylbenzylamines RR′P-C6H4-CH2-NH2 (14-19, R, R′ = H, Me, Ph) with unsubstituted amino groups were also synthesized by this method. The diphenylphosphanyl derivatives 14-16 (R, R′ = Ph) are accessible by an alternative method involving LiAlH4 reduction of the phosphanylbenzonitriles (20-22), which were obtained in high yields by nucleophilic phosphanylation of the corresponding fluoro- or chlorobenzonitriles. The novel bidentate phosphanylbenzonitrile 23 has also been obtained using this synthetic route. All compounds were completely characterized by elemental analysis, NMR spectroscopy, and mass spectrometry.

An efficient synthetic procedure for the preparation of versatile functionally substituted arylphosphines from commercially available starting materials is reported together with alternative routes for (carboxyphenyl)diphenyl phosphines.
