A reaction of bis(triphenylphosphine)palladium dibromide with white phosphorus in the presence of NaBPh4 selectively gives phosphorous acid H3PO3. The mechanism of the formation involves coordination of a white phosphorus molecule, ligand exchange, and hydrolysis of the coordinated P4 molecule in the coordination sphere of palladium.
Synthesis, Characterization, and Thermolytic Behaviour of η3-Allyl(methyl)(tertiary phosphine)palladium(II), and X-Ray Structure of the Cluster 2(μ-Cl)2(μ-dppm)2>*4C4H8O (dppm = Ph2PCH2PPh2)

Complexes of the type 3-allyl)Me(L)> 3, PPh3, PPh2Me, PPhMe2, or PBun3> have been synthesized and characterized by 1H, 13C n.m.r. and mass spectroscopy.The 3-C3H5)Me(L)> complexes thermally decompose with preferential evolution of ethane rather than but-1-ene, the allylic alkylation product.The participation of the binuclear methyl-bridged intermediate 3-allyl)2(μ-Me)2> (3) is supposed.Indirect support for this is given by the thermolysis of a toluene solution of (3).The effects of phosphines, alkenes, and other additives on the thermolysis products are discussed.The structure of a complex isolated from the 3-allyl)2(μ-Cl)2>-LiMe-Ph2PCH2PPh2 (dppm) reaction system in tetrahydrofuran was revealed by X-ray analysis as two μ-chloro-μ-allyl-dipalladium(I) units bridged by two dppm ligands.
