The force constants of the Ni—P bond in P " nickel carbonyl complexes increase in the order MeaP < PHg < P(OMe)a < PFs. This order is different from that of the donor-acceptor character, as estimated from uco-The lengthening of the P—O bond of triphenylphosphine oxide upon complexation with uranium oxide has been estimated by i.r. spectroscopy. However, A -ray diffraction shows little difference in the P-O bond lengths (see Section 7). Some SCF-MO calculations on the donor-acceptor properties of McaPO and H3PO have been reported. 

Figure 3.35 Atomic-charge variations AQ = Q(R) — Q(oo) in dative bonds of H3NO (solid lines), H3PO (dotted lines), and H3AsO (dashed lines). Circles mark oxygen squares mark A atoms of 0 A dative bonds.

Stock Standard solutions of the analytes (100 pg L ) were prepared separately by dissolving appropriate amount of these compounds in 0.1 H3PO. Working solutions were prepared separately by dissolving appropriate amount of these compounds in 0.1 N H3P0 Working solutions were prepared on a daily bases by rigorous dilution of the stocks. 

Powdered drink sample Sahlep) It contains three artificial sweeteners Apt, Ace-K, Sac. An accurately weighted amount of 0.05 g powdered drink (Sahlep) was transferred to 100 mL volumetric flask. The flask was filled up 0.1 N HjPO and agitated 5 min. The solution was diluted 100 mL with 0.1 N H3PO. ... 

Figure 2 Phosphate uptake in DH, cijistallized from 3.5. M H3PO., vs. sulfote content of solution with residence times horn 1200 (circles) to 3600 s, at 60 C (drdes) or 70 C...

SCF calculations for the hypothetical compound H3PO were carried out by Marsmann et al.. The authors studied the effect of adding either a c/ or another p orbital to a phosphorus atom depicted in terms of seven s and three p Gaussian orbitals. An approximate model of H3PO based on the valence bond method has been published by Mitchell. ... 

Nakata showed that stoich. RuOyCCl oxidised steroidal diols to the corresponding ketones [237] electrogenerated RuO from RuO /aq. NaCl/Na(H3PO ) pH 4/ Pt electrodes converted diols to lactones and keto acids (Tables 2.1-2.4) [267] and RuCyaq. 10(0H)3/CC1 -CH3CN oxidised 3-(benzyloxy)-l,2-octanediol to the acid (Tables 3.4, 3.5) [107]. A diol was converted to a lactone by stoicheio-metric oxidation with RuOyCCl as part of the total synthesis of the quassinoid ( )-amarolide [82],... 

Typical examples are listed in Table 2.1. A few oxidations are effected by RuO but in general it is too powerful an oxidant for this purpose. The system RuCyaq. NaCl-CCy Pt anode oxidised benzyl alcohol to benzaldehyde and benzoic acid and p-anisaldehyde to p-anisic acid [24], and a wide range of primary alcohols and aldehydes were converted to carboxylic acids, secondary alcohols to ketones, l, -diols to lactones and keto acids from RuOj/aq. NaCl pH 4/Na(H3PO )/Pt electrodes (Tables 2.1-2.4). The system [RuO ] "/aq. K3(S303)/Adogen /CH3Cl3 oxidised benzyhc alcohols to aldehydes [30]. The oxidation catalyst TPAP (( Pr N)[RuO ]) (cf. 1.3.4) is extremely useful as an oxidant of primary alcohols to aldehydes and secondary alcohols to ketones without...
