Phosphines 684 INDEX

This index is divided by element into eight parts. Each part is subdivided into sections devoted to each oxidation state, preceded by a general section. Thus if you want to fmd out about phosphine complexes of Rhodium, there is a general entry to phosphine complexes as well as separate references to phosphine complexes trader the headings of Rhodium(0), (I), (II) and (III). 

A comparison of bromine and phosphorus compounds on the flammability of PET fiber shows phosphorus (as phosphine oxide) to be 3.7 times more effective than bromine (Table 1). No synergy was observed. Nevertheless, phosphorus was shown to be more effective than antimony normally used as a synergist, resulting in a higher oxygen index at a lower concentration (Table 2). 

Tervalent organophosphorus compounds containing one single P-N bond with the valency of each atom saturated by protons or carbons (but no other heteroatoms) have been known since their discovery by MichaeUs more than one century ago [ 1 ] and named indistinctly as aminophosphanes, phosphanamines, phosphazanes, or phosphinous amides. This last chemical nomenclature is the one used by the Chemical Abstracts Service (CAS) for indexing these compounds and is also the one that best delimits the scope of this review those species derived from the parent H2P-NH2 (phosphinous amide in CAS nomenclature) by partial or total substitution of protons by hydrocarbon radicals (Table 1). 

Fields et al. 33) examined the closely related bis (trifluoromethyl) phosphine (Table 14) and found a similar increase in Vp.H with increasing polarity of the solvent. They noted a correlation between /P H and the proton chemical shift (confidence limit of the correlation coefficient was 99.9 %). Again hydrogen bonding was suggested as the principle causative factor since correlations with dielectric constant or refractive index were not found. The two-bond 2/P F was noted to decrease while the three-bond 3/H F coupling constant was solvent invariant (vide infra).

The refractive index between gaseous phosphine at 0 °C and 760 mmHg and vacuum is 1.000789 when measured with white light. The refractive indices between liquid phosphine and air were found to be, for white light at 11 °C, 1.323 and for the Na-D-line at 17.5 °C, 1.317... 

BMIs and maleimide-terminated prepolymers have been considered for systems with improved Fire, Smoke and Toxicity properties. Of particular interest are phosphorous-containing bismaleimides because they provide high Limiting Oxigen Index (LOI) values (30). 3,3 -bis(maleimidophenyl) methyl phosphine oxide is such a compound (Fig. 7). 

Includes bibliographical references and indexes. Contents v. 1. Primary, secondary, and tertiary phosphines, polyphosphines, and heterocyclic organo-phosphorus(III) compounds—v. 2. Phosphine oxides, sulphides, selenides, and tellurides—v. 3. Phosphonium salts, ylides, and phosphoranes. 

Organic derivatives of phosphine react very vigorously with halogens Individually indexed (unsubstituted) phosphines are ... 

As an illustration, consider the oxidation of acyclic phosphines by bis (2-hydroxyethyl) disulfide which proceeds with retention of configuration at phosphorus. The essential portion of this reaction, and appropriate ligand indexing, are shown in Eq. (13) for the oxidation of (/ )-methylphenyl-propylphosphine (29).
