Abstract: The first nickel-catalyzed phosphorylation of aryltrimethylammonium tetrafluoroborates with the formation of C–P bond instead of C–N has been developed. Starting from easily available and inexpensive aromatic amines, a variety of important arylphosphonates have been synthesized in moderate to excellent yields.

A novel and convenient palladium-catalyzed cross-coupling reaction of H-phosphonate diesters with sodium arylsulfinates was developed via desulfitation in the presence of silver carbonate and tetra-butylammonium chloride. This method is highly efficient and provides a rapid access to a broad spectrum of arylphosphonate diesters in good to excellent yields.

Palladium-catalyzed coupling reaction of diaryliodonium salts with O,O-dialkyl phosphites gave arylphosphonates in good yields.

Trico-ordinate phosphorus compounds, ArnP(OPri)3-n where n = 0-3, react with tetracyanoquinodimethane (TCNQ) in acetonitrile in the presence of water to give the corresponding phosphoryl compounds, ArnP(O)(OPri)3-n and 1,4-bis-dicyanomethylbenzene (TCNQH2) in quantitative yield.The kinetics of these reactions are reported together with the Hammett ρ-parameters from variation of substituents in the aryl group for n = 1,2 and 3.On the basis of the available evidence, a mechanism is proposed involving one electron transfer from phosphorus (the donor) to TCNQ.A kinetic study of the reaction of triarylphosphines with TCNE in aqueous acetonitrile, however, suggests rate-limiting nucleophilic attack on nitrogen rather than the radical cation mechanism.Key words: Tricoordinate phosphorus, tetracyanoquinodimethane, tetracyanoethylene, kinetics, mechanism.
The Kinetics and Mechanism of the Reaction of Tricoordinate Phosphorus Compounds with Diaryl Trisulfides
Hall, C. Dennis,Tweedy, Bruce R.,Kayhanian, Robert,Lloyd, John R.
, p. 775 - 779 (2007/10/02)
Kinetic data and activation parameters are reported for the reaction of a series of tricoordinate phosphorus compounds, , with diaryl trisulfides.The second-order rate coefficients for series of arylphosphines, phosphinites and phosphonites, correlate with the Hammett ? constants of the aryl substituents with ρ values of -1.1, -1.1 and -1.1 respectively and these results are discussed in terms of a biphilic mechanism analogous to that proposed for the reaction of tricoordinate phosphorus with S8.
