Reaction with aluminum nitrate

Active metals such as aluminum and zinc in alkaline solution reduce nitrate to ammonia. Nitrite ion will also form ammonia under these conditions. Devarda s alloy (50% Cu, 45% Al, 5% Zn) gives the following reaction with nitrate ion ... 

A,iV-DIMETHYLMETHANIDE (68-12-2) Forms explosive mixture with air (flash point 136°F/58 C). Violent reaction with nitrates, carbon tetrachloride, hexachlorocyclohexane, and other halogenated compounds, particularly in contact with iron or strong oxidizers, may cause fire and explosions. Vigorous reaction with alkylaluminums. Incompatible strong acids, allyl trifluoromethanesulfonates, ammonia, chlorinated hydrocarbons, cresols, chromic anhydride, isocyanates, nitrates, phenols, magnesium nitrate, methylene diisocyante, phosphorous trioxide, triethyl aluminum. Attacks some plastics and coatings. 

Nitration of hydroxypropiophenone (7-1) followed by conversion of the phenol to its methyl ether by means of methyl iodide provides the intermediate (7-2) the nitro group is then reduced to the corresponding amine (7-3) by catalytic reduction. The newly introduced amine is then replaced by a nitrile group by successive conversion to the diazonium salt by means of nitrous acid followed by treatment with cuprous cyanide (7-4). Reaction with aluminum chloride removes the methyl ether to afford the ortho acylphenol (7-5). This is converted to the chromone (7-6) as above by reaction with benzoyl chloride and sodium benzoate. The nitrile is next hydrolyzed to the carboxylic acid (7-7) by means of sulfuric acid. The acid is then converted to its acid chloride by means of thionyl chloride and that treated with 2-(A -piperidyl)ethanol (7-8). There is thus obtained flavoxate (7-9) [8], a muscle relaxant whose name reflects its flavone nucleus. 

Nitryl chloride reacts with zinc, mercury, and bismuth to form mixtures of the metal chlorides and nitrates, but does not react with copper, magnesium, iron, aluminum, or tin at 243 K. In the reaction with ammonia, nitryl chloride acts as a source of positive chlorine ...

Benzo[c]cinnoline forms molecular complexes with halogens in organic solvents thus attempts to brominate it with molecular bromine have been unsuccessful. Using a source of positive bromine, bromine/silver sulfate in sulfuric acid, Corbett and Holt found that reaction occurred at room temperature to give 27% of a monobromo and 4% of a dibromo derivative. These compounds were at first identified as 1-bromo- and l,4-dibromo-(or l,7-dibromo-)benzo[c]cinnolines, but the former was subsequently shown to be the 4 isomer. A reinvestigation of the reaction has shown that both 1- and 4-bromobenzo[c]cinnolines are primary products, formed in the ratio of ca. 2.3 1 at room temperature. The lower isomer ratio as compared with nitration in sulfuric acid probably reflects the greater steric demand of the attacking species. The dibromo compound formed is the 1,4-isomer. The formation of the octachloro derivative by chlorination of benzo[c]cinnoline in the presence of aluminum chloride has been mentioned,but no details are available. 

Among the simple catalysts that have been proposed oxides of zinc,09 cadmium, lead, bismuth, silicon, aluminum, titanium may be mentioned.5,0 Alkaline materials as sodium or calcium carbonates have also been claimed. The zinc oxide catalyst is prepared by spraying a solution of zinc nitrate, alone or with nitrates of other metals, on pumice and then heating the product in air. In practice the phthalic anhydride is simply steam dis-stilled into the reaction chamber and the products separated by fractional condensation or selective solution.
