In a later paper Speziale and Smith 109) investigated the reaction of trivalent phosphorus compounds with N-monosubstituted a-trichloro-acetamides and a-trichloroacetamide. The products were imidoyl chlorides (129) and dichloroacetonitrile (130), respectively. The intermediacy of enamines (131) was assumed. For the monosubstituted amides the enamine... 

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. ... 

Biodegradation. Under aerobic conditions, biodegradation results in the mineralization of an organic compound to carbon dioxide and water and—if the compound contains nitrogen, sulfur, phosphorus, or chlorine—with the release of ammonium (or nitrite), sulfate, phosphate, or chloride. These inorganic products may then enter well-established geochemical cycles. Under anaerobic conditions, methane may be formed in addition to carbon dioxide, and sulfate may be reduced to sulhde. 

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... 

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. 

The compound is produced by evaporating hydrochloric acid solutions of polonium (IV) 6, 26, 74), by heating the dioxide in carbon tetrachloride vapor 74), in hydrogen chloride, thionyl chloride or with phosphorus pentachloride 6) and by heating the metal in dry chlorine at 200°C (6, 25, 74). It is hygroscopic and hydrolyzes in moist air to a white solid, possibly a basic chloride (7)). The tetrachloride is soluble in thionyl chloride and in water with hydrolysis, and is moderately soluble in ethanol, acetone, and... 

Zirconium(IV) chloride reacts with P(NCO)3 in benzene and with P(CN)3 in benzene-diethyl ether to give the substitution products ZrCl3 P(NCO)2 and ZrCl3 P(CN)2, respectively (equation 25). These compounds have been obtained as somewhat impure, very hygroscopic solids. On the basis of IR evidence, the P(NCO)2 and P(CN)2 ligands are believed to be coordinated through the phosphorus atom.138... 

Many examples exist where the open chain betaine may be quenched by reagents, giving stable phosphorus compounds with P-C1V = 3. When (180) is reacted with acetyl chloride the open chain enol phosphate (181) is formed. Many interesting O- and N-phosphaspirans are also mentioned in (75BSF407). 

Concentrated hydrochloric acid also dissolves the trichloride, about 100 g. of the latter dissolving in 1 litre of acid at 100° C.7 Dissolution in hydriodic acid is accompanied by evolution of heat and the triiodide is formed.8 Ethyl iodide reacts similarly.9 Double decomposition reactions occur w hen arsenic trichloride is heated with phosphorus triiodide, stannic iodide or germanium iodide, the reactions being complete.10 Similarly, potassium iodide heated with arsenic trichloride in a sealed tube at 210° C., and potassium bromide at 180° to 200° C., form respectively arsenic triiodide and tribromide.11 Stannous chloride, added to the solution in hydrochloric acid, causes reduction to arsenic (see p. 29). Arsenic trichloride may be completely separated from germanium chloride by extraction with concentrated hydrochloric acid.12 Ammonium, sodium and cobaltic chlorides react with arsenic trichloride to form additive compounds with magnesium, zinc and chromic chlorides there is no reaction.13...
