Hydrazinium halides

Attempts to obtain complexes with the 16-membered octaazamacrocycle L44 by interaction of diacetyl with hydrazinium halides, followed by the subsequent addition of nickel(II) or copper(Il) salts and prolonged heating of the reaction mixture, led to the isolation of [M(L45)]X2 H20, where X = Cl , Br , N03 , C104 or BF4 andn = 0,2(Eq. 2.8) [13],... 

Tertiary Amines.—A variety of new and improved methods for the synthesis of tertiary alkylamines have been reported, " the most novel of which appears to be the alkylative amination of non-enolizable aldehydes using the readily available tris(diethylamino)methyltitanium and related compounds (Scheme 17), Although the deamination of quaternary hydrazinium halides is known. 

Similar to hydrazine hydrate, a good reducing agent, other inorganic salts like hydrazinium sulfate and hydrazinium halides are also used as reducing...

Reaction of MA with mixtures A,A-dimethylhydrazine and alkyl halide in the presence of a base gives rise to an aminimide derivative 118/276,277) Preformation of the hydrazinium salt by reaction of 7V,A-dimethylhydrazine... 

The most adequately characterized hydrazinium complexes consisting of coordinated metal ions are (N2H5)2M(S04)2 (M = Mg, Mn, Fe, Co, Ni, Cu, Zn, Cd, and the halides) [31]. In addition, single crystals have been analyzed of Co and Ni double sulfates synthesized under hydrothermal conditions using metal sulfates, hydrazine hydrate, and HF [32]. Table 1.8 lists various hydrazinium compounds along with their crystal data and N—N bond distances.
