We have noted that N-bonded thiocyanate complexes dissociate readily in solution. Mixed ligand complexes of lanthanides with thiocyanates and L = ethanol, pyridine, triphenyl phosphorous oxide, phenanthroline, etc. have been synthesized.

This property of organophosphate esters may be of environmental importance since phosphoric acid diesters are much more soluble and very little is known concerning the environmental toxicity of these compounds. The available data do not provide sufficient descriptions of the experimental methods to determine if the rates are reliable (Barnard et al. 1961 Ciba-Geigy 1984e, 1986 Howard and Deo 1979 Mayer et al. 1981 Wolfe 1980). The majority of reports provide only a minimum of information and exclude important facts such as the duration of the experiments and the concentration of buffers. Despite the lack of experimental detail, published rate constants for base-catalyzed hydrolysis appear to be reasonably consistent and suggest that the hydrolytic half-life of triphenyl phosphate will vary from... 

We went back and looked at that system, because we thought it had quite a bit of promise. It turns out that, with triphenyl phosphine, platinum(O) will attack the phosphorous phenyl bonds to produce red polymers which are phosphido-bridged platinum species. But we were more interested in the small alkyl phosphines, because we expect those to make the metal center even more reactive (being sterically unhindered and more basic).

Carbon-13 shifts of representative phosphines [364], phosphonium salts [365], phospho-nium ylides [365, 366], diphosphines [367], phosphonates [368], phosphorous and phosphoric acid derivatives [369] are summarized in Table 4.49. I3C shift data of some group V organoelement compounds are compared in Table 4.50. It turns out that a sp3 carbon nuclei of phosphines and arsines are shielded (0-25 ppm) relative to those of amines (30-60 ppm), as expected from the heavy atom effect, sp2 carbons of CC double bonds behave correspondingly, as shown for the triphenyl derivatives in Table 4.50, with... 

It was stated that the wavelengths of the absorption bands of elements are higher than those of their compounds, and that the bands pass to shorter wavelengths as the valency rises, provided that the successively attached atoms or radicals are the same. The general results showed that the structural formulae of the phosphorous diesters, triphenyl-methylphosphorous acid and ferric monopropyl phosphite were (RO)2 =PO — (H), sodium diethyl phosphite (EtO)2PO(Na), silver diethyl phosphite (EtO)2P(OAg), monoacetylphosphorous acid (HO)2 PO(Ac). In solution, the diesters and metal esters contained a mixture of tautomeric forms.3... 

Phosphorous acid, H3PO3, is generated by hydrolysis of PCI3 - industrially this is carried out by spraying the chloride into steam at 190 °C. Esters of the acid, both the triaUcyl esters [P(OR)3] and the diaUcyl esters [(RO)2P(0)H], can be produced directly by substituting the appropriate acid for the water. The esters find much use thus, triphenyl phosphite is most widely used in the manufacture of polyvinyl chloride, while trinonylphenyl phosphite is an excellent stabilizer for the same polymer.
