Ready Approach to Organophosphines from ArCl via Selective Cleavage of C-P Bonds by Sodium

The preparation, application, and reaction mechanism of sodium phosphide R2PNa and other alkali metal phosphides R2PM (M = Li and K) have been studied. R2PNa could be prepared, accurately and selectively, via the reactions of SD (sodium finely dispersed in mineral oil) with phosphinites R2POR′ and chlorophosphines R2PCl. R2PNa could also be prepared from triarylphosphines and diarylphosphines via the selective cleavage of C-P bonds. Na was superior to Li and K for these reactions. R2PNa reacted with a variety of ArCl to efficiently produce R2PAr. ArCl is superior to ArBr and ArI since they only gave low yields of the products. In addition, Ph2PNa is superior to Ph2PLi and Ph2PK since Ph2PLi did not produce the coupling product with PhCl, while Ph2PK only gave a low yield of the product. An electron-withdrawing group on the benzene ring of ArCl greatly accelerated the reactions with R2PNa, while an alkyl group reduced the reactivity. Vinyl chloride and alkyl chlorides RCl also reacted efficiently. While t-BuCl did not produce the corresponding product, admantyl halides could give the corresponding phosphine in high yields. A wide range of phosphines were prepared by this method from the corresponding chlorides. Unsymmetric phosphines could also be conveniently generated in one pot starting from Ph3P. Chiral phosphines were also obtained in good yields from the reactions of menthyl chlorides with R2PNa. Possible mechanistic pathways were given for the reductive cleavage of R3P by sodium generating R2PNa and the substitution reactions of R2PNa with ArCl generating R2PAr.

Water soluble phosphines VIII. Palladium-catalyzed P-C cross coupling reactions between primary or secondary phosphines and functional aryliodides - A novel synthetic route to water soluble phosphines

Tertiary phosphines Ph2P-Ar and PhP(Ar)2 containing mono-and disubstituted aromatic ring systems Ar (Ar = C6H4-X and C6H3-XY; X, Y = Me, OH, NH2, COOH, COOMe and SO3Na) are accessible in good yields by Pd(0)-catalyzed cross coupling reactions between diphenylphosphine or phenylphosphine and substituted aryliodides I-C6H4-X or I-C6H3-XY in organic solvents (dimethylacetamide, acetonitrile, methanol) using organic amines or potassium and sodium acetate as bases.
