Magnesium/alcohols hydrazines

Method I Magnesium perchlorate hydrazine, Mg(Cl04)2(N2H4)2 is prepared by the addition of hydrazine hydrate to an aqueous solution of magnesium perchlorate hexahydrate (2 1 ratio, respectively) at room temperature. The reaction is almost instantaneous and the solid compound is precipitated by the addition of alcohol (90% product yield) ... 

Method II Magnesium perchlorate hydrazine can also be prepared by the reaction of stoichiometric quantities of magnesium powder with ammonium perchlorate dissolved in hydrazine hydrate (1 2 2 ratio, respectively) at room temperature. Magnesium metal dissolves exothermically with the evolution of hydrogen. The solid compound is obtained by the addition of alcohol ( 96% yield) ... 

Chloro-5,6-diphenyl-as-triazine readily undergoes methoxy-de-chlorination at 25° (< 12 hr) with methanolic methoxide and at 65° (4.5 hr) in non-basified methanol. The chloro group is also displaced by hydrazine (80°, 1 hr), ammonia (140°, 6 hr), and phenyl-magnesium bromide (70°, 12 hr), the latter forming the triphenyl compound 315.3-Chloro-6-phenyl-as-triazine is unstable to cold water or alkali and to hot alcohol or aqueous potassium carbonate. ... 

Bromonaphthalene has been reduced to naphthalene in good yield by hydrogenation over Raney nickel in methanolic potassium hydroxide, by triphenyltin hydride in benzene, by magnesium in isopropyl alcohol, by sodium hydrazide and hydrazine in ether, and by copper(I) acetate in pyridine. ...

The V(OH)2/Mg(OH)2 gel is believed to be a solid solution with a lattice similar to Cdl2, and the yield of hydrazine reaches a maximum with the magnesium to vanadium ratio in the range 1 5-10 (133). Shilov finds (1) no 14N isotope effect corresponding to the Schrauzer mechanism, (2) that there is no evidence for vanadium IV), (3) that the reduction of allyl alcohol is independent of, and competitive with, dinitrogen reduction, and (4) a different dependence on P 2 from the square dependence claimed. In short, no evidence for diazene, but much more for a direct reduction to hydrazine (136). 

FERROUS CHLORIDE TETRA-HYDRATE (7758-94-3) FeCl Contact with ethylene oxide may initiate polymerization. Reacts violently with reducing agents, including hydrides, nitrides, and sulfides acrolein, alcohols, chlorine trifluoride, ethers, fluorine, hydrazine, hydrazinium perchlorate, hydrogen peroxide, finely divided aluminum or magnesium, peroxyfuroic acid, sodium acetylide. Sensitizes most organic azides which are unstable shock and heat-sensitive explosives. Forms explosive materials with l,3-di(5-tetrazoyl)triazene, potassium,sodium. Incompatible with glycidol, isopropyl chlorocarbonate, nitrosyl perchlorate, sodium borohydride. Aqueous solution attacks metals.
