About 80-90% of the elemental P produced is reoxidized to (pure) phosphoric acid (p. 521). The rest is used to make phosphorus oxides (p. 503). sulfides (p. 506), phosphorus chlorides and oxochloride (p. 4%). and organic P compounds. A small amount is convened to red phos rftorus (see below) for use in the striking surface of matches for pyrotechnics and as a flame retarding agent (in polyamides). Bulk price for P4 is S2.00/kg.

A comprehensive review of the preparation, reactions, and n.m.r. spectra of phosphorus-fluorine compounds has appeared. This year s literature has been notable for the first detailed applications of ab initio SCF-MO calculations to the problems of bonding in halogenophosphines and their derivatives. - Comparison of the results of such theoretical calculations with experimental data obtained from photoelectron spectra shows a good correlation in the case of phosphorus trichloride and phosphoryl chloride, and of phosphorus trifluoride and its borane complex. ... 

The reactions of tri-ATZ-butylplumbyllithium with various phosphorus chlorides have been investigated. For example, reaction of the lithium compound with diphenylchlorophosphane afforded hexa-tert-butyldiplumbane and tetraphenyldiphosphane as the isolated products. Analogous reactions with -butyl-substituted phosphorus chlorides yielded (tri-A, 7-butylplumbyl)di- -butylphosphane or tri- z -butylplumbyl(amino)-, t -butylphosphane. These and other molecules were characterized by multinuclear magnetic resonance spectroscopic studies.24... 

The isomeric 1,3-dioxino[4,5-/i]quinoline (698) and l,3-dioxino[5,4-/i]quinoline (700, R = Me) were prepared by cyclization of the appropriate N-( 1,3-benzodioxanyl)aminomethylenemalonates (697 and 699, R = Me) in boiling phosphoryl chloride for 12 hr (72MI5). While the methyl derivative of compound 699 (R = Me) readily gave l,3-dioxino[5,4-/i]quinoline (700, R = Me), the unsubstituted and chloro derivatives (699, R = H, Cl) could not be cyclized by heating in phosphorus chloride, even if triethylamine, SnCl4, or PC15 was also present (72MI5). 

Other synthetic routes to phosphazenes, using phosphorus(v) compounds as substrates, are more limited. An example of the reaction of a nitrile with a phos-phorus(v) chloride is provided by Scheme 4.48 In benzene solution, or in the absence... 

Recently, sulfinyl and sulfonyl peroxy radical intermediates 6a and 6b have been prepared by the reactions of aryl sulfinyl or sulfonyl chloride with superoxide anion radical, respectively. These peroxy intermediates show strong oxidizing abilities in various oxidations. This chapter will describe the properties and applications of a variety of sulfur and phosphorus peroxy compounds in oxidation reactions. For a more complete picture, readers should consult the original papers cited in the areas that most interest them. 

Lactams react with phosphorus chlorides to yield the corresponding chloro compounds as in the uracil (117) (70GEP1950990). 

The chloride compound is obtained by electric discharge in a mixture of PC13 and H2. Preparation of P2I4 can be carried out by the reaction of I2 with a carbon disulfide solution of white phosphorus. 

That the three ordinary valencies of phosphorus in compounds of the type POX3 or PQR3 do not act in one plane, but are distributed in space symmetrically with respect to one another, was demonstrated by Caven,1 who replaced chlorine atoms in the trichloride one at a time taut in different succession by various groups such as RNH— or RO—, forming, for example, the anilino-, p-toluidino- and then the P toluidino-anilino chloride. 

The BCD is very sensitive to phthalate esters, for example di(2-ethylhexyl) phthalate which is a common contaminant of blood stored in polyvinyl chloride containers (Fig. 1). The AFID can be made virtually specific for phosphorus-containing compounds, but retains its capability to detect phosphorus even when optimised for nitrogen compounds. The contaminant tri-isobutyl phosphate from filter paper is not apparent when using the FID, but produces the largest peak on the chromatogram with the AFID in the nitrogen mode (Fig. 2). 

Organolithium compounds can also react with fluorinated phosphorus derivatives. For example, aryl(difluoio)phosphanes 18 are formed by reaction of the corresponding aiyllithium compounds with phosphorus chloride difluoridc. The overall reaction is shown in Table I. This procedure has also been extended to the preparation of several cyclopentadienyl(di-fluoro)phosphane derivatives. ...
