Interaction of anhydrous hydrazine and titanium isopropoxide is explosive at 130° C in absence of solvent. Evaporation of solvent ether from the reaction product of tetrakis(dimethylamino)titanium and anhydrous hydrazine caused an explosion, attributed to formation and ignition of dimethylamine. /V-Metal derivatives may also have been formed. [Pg.1677]

An alternative hydrazine derivative used is 3 -methyldithiocarbazate, which is reported to react with tetracya-noethylene via a charge-transfer complex, giving a mixture of polysubstituted pyridazine 9 and pyridazino[4,5-rfjpyridazine 10 <1995PS(101)189>. l,4,5,8-Tetrakis(4-methoxyphenyl)pyridazino[4,5-4]pyridazine 11 has also been prepared by cyclization of tetrakis(4-methoxyphenyl)ethane with hydrazine itself <2000RJ01157>. [Pg.984]

Methods (i) and (ii) require palladium(II) salts as reactants. Either palladium acetate, palladium chloride or lithium tetrachloropalladate(II) usually are used. These salts may also be used as catalysts in method (iii) but need to be reduced in situ to become active. The reduction usually occurs spontaneously in reactions carried out at 100 °C but may be slow or inefficient at lower temperatures. In these cases, zero valent complexes such as bis(dibenzylideneacetone)palladium(0) or tetrakis(triphenylphos-phine)palladium(O) may be used, or a reducing agent such as sodium borohydride, formic acid or hydrazine may be added to reaction mixtures containing palladium(II) salts to initiate the reactions. Triarylphosphines are usually added to the palladium catalysts in method (iii), but not in methods (i) or (ii). Normally, 2 equiv. of triphenylphosphine, or better, tri-o-tolylphosphine, are added per mol of the palladium compound. Larger amounts may be necessary in reactions where palladium metal tends to precipitate prematurely from the reaction mixtures. Large concentrations of phosphines are to be avoided, however, since they usually inhibit the reactions. [Pg.835]

The formation of the silylhydrazines depends on the reactivity and the bulkiness of the halosilanes. The condensation increases with increasing number of the hydrogen atoms. While iodosilane or bromo(methyl)-silane yield the tetrakis(silyl)hydrazines,912... [Pg.2]

The first unsymmetrically substituted tetrakis(silyl)hydrazine that was determined by a crystal structure is the IV,jV -[bis(difluorophenylsilyl)]-/V,Ai -[bis(trimethylsilyl)]hydrazine 83 [see Eq. (22)].16 Like those of 77 and 79, the N atoms of 83 show a planar coordination geometry, as the angle sum is found to be 360°. Because of the electron withdrawing effect of the fluorine atoms, these Si—N bonds are shortened compared to the other Si—N bonds of this molecule (Table XIV). The fluorine atoms of... [Pg.23]
