With Nitrogen-Containing Compounds

Reactions of PH3 with CH2=CHCN, CH2=CHCH2NH2, and CH2=CHCH2N(C2H5)2 are described in the section covering the reactions with alkenes see Table 18, pp. 273/4. 

Reactions of PH3 with (CH3)3N at an approximately 1 2 molar ratio at, e.g., 300 C in a solid-bed reactor filled with active carbon (residence time 64 s) yield CH3PH2 (67.5%), (CH3)2PH (27.3%), (CH3)3P (2.5%), and phosphorus (yields in parentheses refer to 90% PH3 converted). Shorter residence times or a PH3 (CH3)3N mole ratio 1 2 favor formation of the primary phosphane. Longer residence times, higher temperatures, and a low PH3 (CH3)3N mole ratio ifavor the formation of the secondary and tertiary phosphane. In a fluid-bed reactor filled with finely dispersed Si02 covered with a layer of Cu or Ni at 350 C and 7 to 8 s residence time, 

PH3 and (CF3)2C=NH condensed together at -196 C react on warming to ambient temperature during 2 days to give NH2C(CF3)2PH2 [168]. 

PH3 (2 to 4 atm) reacts with organic isocyanates, XC6H4NCO (X = H, p-Cl, P-NO2 [172] a77-CH3 [173]), in benzene in the presence of triethylamine or tributylamine to give tricarbamoyl-phosphanes, (XC6H4NHC(0))3P. Ethyl, octyl (in the presence of tripropylamine at lOO C and 340 atm), or 1-naphthyl isocyanate react analogously [173]. The reaction of 2,4-tolylene diisocyanate with PH3 is slow, and no definite product could be isolated. Phenyl isothiocyanate failed to react with PH3 under reaction conditions analogous to those for the isocyanates [172]. 

The behavior of heptafluoroazacyclopentane-2-one towards PH3 is quite different to that of hexafluorocyclobutanone (cf. p. 279). Ring expansion occurs instead of PH3 addition to give a diazacyclodecanedione derivative, PF3, and an unidentified orange solid [174].

Complexes of B-heterocycles with nitrogen-containing compounds 99JOM(581)129. 

Iron can be controlled with certain complexing agents, in particular glucono-5-lactone, citric acid, ethylenediaminetetraacetic acid, nitrilotriacetic acid, hydroxyethylethylene diaminetriacetic acid, hydroxyethyliminodiacetic acid, and the salts from the aforementioned compounds. These compounds must be added together with nitrogen-containing compounds such as hydroxylamine salts or hydrazine salts [486,643,1815]. 

Additional products of the myeloperoxidase system depend upon the local environment. For example, HOC1 can react with nitrogen-containing compounds such as biological amines to form chloramines ... 

The activity in the field of ferroceno heterocyclic compounds of the type 1 has been even less in the case of oxygen-containing compounds than it was with nitrogen-containing compounds. As might be anticipated, the first two examples of this class of compounds were an anhydride and a lactone. Thus treatment of ferrocene-1,2-di carboxylic... 

Hydrogen bonds may also occur with nitrogen-containing compounds such as the oxime formed from aniline and salicylaldehyde (V and VI)... 

ISOCYANURIC CHLORIDE (87-90-1) A powerful oxidizer. Violent reaction with reducing agents. Reacts with acrolein, antimony trisulfide, antimony tritelluride, arsenic pentasul-fide, 1,1-dichloro-l-nitroethane, 1,3-dichloropropene, diethylamine, s-trioxane. Incompatible with m-bis(trichlormethyl)benzene. Reacts with nitrogen-containing compounds ammonia, amines, urea, forming the unstable explosive nitrogen trichloride. Contact with combustible material, organic substances may cause fire. 

There have been several studies of reactions of alkali-metals with nitrogen-containing compounds NO2 [103, 104, 142], CH3NO2 [103, 104], C2H5ONO2, iso-CsHi,ONO and N2O [104], BrCN, ICN and NOCl [176] and K2/BrCN [180]. 

The content of elements in the nutritional chain is affected by chemical characteristics of the elements, soil composition, plant species, time of harvesting and many other factors. For example, changes of pH of soils after applications of calcium can be manifested in plants by an increased intake of molybdenum and reduced concentrations of copper, iron, manganese and zinc. An increased intake of phosphorus, nitrogen and potassium by plants is manifested by a reduction in the intake of sodium and magnesium by farm animals. Intense fertilization with nitrogen-containing compounds also induces a decrease of the content of copper and zinc in plants, which is manifested adversely in the intake of these elements by animals [5].
