Complexes of triphenylphosphine

With cobalt(ii) chloride, complexes of the monophosphazene, PhgP=NH (= L), of stoicheiometry CoCl2L,THF and C0CI2L2 have been isolated. Their i.r. and u.v. spectra were compared with analogous complexes of triphenylphosphine oxide. 

The analogous formation of aryl stannanes and aryl germanes from aryl halides occurs in the presence of catalytic amounts of palladium complexes of triphenylphosphine. Hexabutyl-... 

The distribution of the catalyst depends on the choice of the non-polar solvent and on the ligand used. With cyclohexane and the alcohols the palladium complexes of tricyclohexylphosphine and triphenylphosphine are located in the polar phase, with p-xylene the complex of triphenylphosphine is dispersed in both phases, and the complex of tricyclohexylphosphine can be predominantly found in the non-polar phase. Because of the low solubility of... 

Palladium compounds have also been reported to stabilize unexposed areas to heat.199 The compounds disclosed include the complexes of triphenylphosphine, bipyridine, acetylacetone and dimethylglyoxime. Preferred compounds appear to be the acac analogs.

IRON CARBONYL COMPLEXES OF TRIPHENYLPHOSPHINE, TRIPHENYLARSINE, AND TRIPHENYLSTIBINE... 

Tributylphosphine sulfide has been used as a co-catalyst with dicobalt octacarbonyl for the Pawson-Khand reaction. Thermolysis of a mixture of cadmium chloride and trioctylphosphine sulfide at 250 °C has been used as a route to the formation of nanocrystalline cadmium sulfide." A complex of triphenylphosphine sulfide with a silver-tungsten-iodine acceptor has been characterised by X-ray studies. Ferrocenylphosphine chalcogenides have attracted considerable interest as ligands. Complexes of the monophosphino-phosphine sulfide (269) with rhodium have been characterised." The disulfide (270) forms complexes with both gold(i) and gold(iii) acceptors," and a silver(i) complex of the diselenide (271) has been prepared. ... 

In view of the current interest in highly sterically hindered aryl phosphorus compounds the report of dipole moment studies of trimesityl- and triphenyl-phosphine oxides is worth noting. The thermodynamics of hydrogen-bonded complexes of triphenylphosphine oxide and various alkylarylphosphine oxides with a number of hydroxyl-containing compounds have been studied.
