Hydrazinium salt

Hydrazinium salts, N2H5 X, are acids in anhydrous hydrazine, metallic hydrazides, N2H, are bases. Neutralization in this solvent system involves the hydrazinium and hydrazide ions and is the reverse of equation 7. Metal hydrazides, formally analogous to the metal amides, are prepared from anhydrous hydrazine and the metals as well as from metal amides, alkyls, or hydrides. (The term hydrazide is also used for organic compounds where the carboxyUc acid OH is substituted with a N2H2.) Sodium hydrazide [13598-47-5] is made from sodium or, more safely, from sodium amide (14) ... [Pg.275]

Hydrazinium salts form by simple neutralization using the corresponding acid. Two series of salts are possible, containing the hydrazinium(I) ion,, ... [Pg.276]

Hydrazine as Nucleophile. Reaction of hydrazine and carbon dioxide or carbon disulfide gives, respectively, hydrazinecarboxyhc acid [471-31-8], NH2NHCOOH, and hydrazinecarbodithioic acid [471-32-9], NH2NHCSSH, in the form of the hydrazinium salts. These compounds are useful starting materials for further synthesis. For example, if carbon disulfide reacts with hydrazine in basic medium with an alkyl haUde, an alkyl dithiocarbazate ester is obtained in a one-step reaction ... [Pg.276]

The aqueous solution chemistiy of nitrous acid and nitrites has been extensively studied. Some reduction potentials involving these species are given in Table 11.4 (p. 434) and these form a useful summaiy of their redox reactions. Nitrites are quantitatively oxidized to nitrate by permanganate and this reaction is used in titrimetric analysis. Nitrites (and HNO2) are readily reduced to NO and N2O with SO2, to H2N2O2 with Sn(II), and to NH3 with H2S. Hydrazinium salts yield azides (p. 432) which can then react with further HNO2 ... [Pg.462]

The triazoloxazine 294 containing the saturated oxazine moiety was synthesized by Knight and Leeper <1998J(P1)1891> treatment of the hydrazinium salt 293 with trimethyl orthoformate yielded the product 294 in quantitative yield. [Pg.711]

Hydrazinium lodate. N2H4-HI03 has been postulated to exist only in cold solutions (Ref 4). In general, hydrazinium salts of oxidizing acids are much less stable than the corresponding ammonium salts Refs 1) G.F. Smith, ChemEngNews 29, 1770 (1951) CA 46, 3279 (1951) 2) Cs. [Pg.382]

Tertiary amines. A new preparation of tertiary amines involves alkylation of 1,1 -dimethylhydrazine2 (9,184-185 and earlier volumes) followed by deamination of the resulting hydrazinium salt with nitrous acid in 4 A HC1. [Pg.588]
