Sodium diethylaluminum

GB 1 469 014 (Denki Kagaku Kogyo appl. 30.9.1974 J-prior. 28.9.1973). reduction with sodium diethylaluminum hydride ... 

Formation of diethylaluminum cyanide from triethyl-aluminum and hydrogen cyanide was noted initially by the submitters and later by Stearns, but isolation and characterization of the product were first performed by the submitters. An unpractical process comprising heating diethylaluminum chloride and sodium cyanide in benzene for 21 days has been reported. ...

Deviations from this general behavior are found with various alkyl aluminum alcoholates. Since alkoxy ions, OR, are stronger Lewis bases than the halogen ions, the Lewis acidity of the dialkylalkoxy alanes formed with the hypothetical Lewis acid R2A1+ (32) is low, i.e., there is little tendency to form complexes with weak bases. Accordingly, diethylaluminum alcoholate forms stable salts with potassium and cesium fluoride but not with sodium fluoride. The tendency to form complexes (e.g., with KF and NaH) increases in going from R2A10R to RAl(OR)2 (Fig. 9) (156, 322). Thus the... 

BROMURE d ETHYLE (French) (74-96-4) Forms explosive mixture with air (flash point —4°F/—20°C). Hydrolyzes in water, forming hydrogen bromide. Contact with oxidizers, diethylaluminum hydride, chemically active metals aluminum, magnesium, or zinc powders lithium, potassium, sodium may cause fire or explosions. Incompatible with alcohols, diketene. Attacks some plastic, rubber, and coatings. 

NITROCARBOL (75-52-5) Forms explosive mixture with air (flash point 95°F/35°C). Thermally unstable. Shock, friction, pressure, or elevated temperature above 599°F/315°C can cause explosive decomposition, especially if confined. Violent reaction with strong oxidizers, alkyl metal halides, diethylaluminum bromide, formic acid, methylzinc iodide. Contact with acids, bases, acetone, aluminum powder, amines, bis(2-aminoethyl)amine, haolforms make this material more sensitive to explosion. Reacts, possibly violently, with ammonium hydroxide, calcium hydroxide, calcium hypochlorite, 1,2-diaminomethane, formaldehyde, hexamethylbenzene, hydrocarbons, hydroxides, lithium perchlorite, m-methyl aniline, nickel peroxide, nitric acid, metal oxides, potassium hydride, potassium hydroxide, sodium hydride. Mixtures with ammonia, aniline, diethylenetriamine, metal oxides, methyl amine, morpholine, phosphoric acid, silver nitrate form shock-sensitive compounds. Forms high-explosive compound with urea perchlorate. Mixtures with hydrocarbons and other combustible materials can cause fire and explosions. Attacks some plastics, rubber, and coatings. 

The Nicholas reaction, that is, the addition reaction include amines, water, alcohols, trialkylaluminum reagents, of nucleophiles to cobalt-complexed propargylic cations, sodium borohydride, diethylaluminum cyanide, trialkylsilyl...

The dispersion polymerizations of s-caprolactone and lactides were initiated with initiators used for initiation of polymerizations of the above-mentioned monomers in solution. Diethylaluminum ethoxide, stannous 2-ethylhexano-ate, ° stannous 2-ethylhexanoate/polyalcohols, and 2,2-dibutyl-2-stanna-l,3-dioxepane were used for the dispersion polymerizations of lactides. The dispersion polymerizations of 8-caprolactone were initiated with diethylaluminum ethoxide and sodium trimethylsilano-late. Of the above-mentioned initiators, only the latter one initiated the anionic polymerization.
