COPPER DINITRATE (3251-23-8) A strong oxidizer. Violent reaction with reducing agents, combustible materials, acetic anhydride, ethers, potassium ferrocyanide, finely divided tin. The aqueous solution is a medium-strong acid. Incompatible with bases, acetylene, ammonia, aliphatic amines, aikanolamines, amides, alkylene oxides, cyanides, epichlorohy-drin, esters, isocyanates, organic anhydrides, vinyl acetate. Attacks metals in the presence of moisture.

M[pz(A4)] A = S2ML2. The octakis(.V-R)porphyra/,ines reported by Schramm and Hoffman (2), M[pz(S-R)8 (M = Ni, Cu), (60), can be converted to the octathiolate M[pz(S )g] (Scheme 11) via reductive cleavage of the sulfur-carbon bond when R = benzyl (Bn), and this tetra-bis(dithiolate) can then be peripherally capped with metal-ligand systems to yield peripherally tetrametalated star porphyrazines. The benzyl dinitrile 57 can be macrocyclized around magnesium butoxide to form [Mg[pz(S-Bn)8] (58) (35-40%), which can then be demetalated with trifluoroacetic acid to form 59 (90%), which is subsequently remetalated with nickel or copper acetate to form 60a (95%) and 60b (70%) (Scheme 11) (3, 23, 24). Deprotection of 60a or 60b with sodium in ammonia yields the Ni or Cu tetra-enedithiolates, 61a or 61b to which addition of di-ferf-butyl or n-butyl tin dinitrate produces the peripherally metalated star porphyrazines 62a (37%), 62b (80%), and 62c (41%). 

Normally, nitration of deactivated compounds (and therefore polynitration of toluene) is carried out using aggressive nitric acid - oleum mixtures. Dinitration of toluene with mixed acids produces a 4 1 ratio of 2,4- and 2,6-dinitrotoluenes, from which the former is isolated for manufacture of toluenediisocyanate (TDI) and toluenediamine, both of which are used in the manufacture of polyurethanes. Zirconium and hafnium derivatives catalyse nitration of o-nitrotoluene, but ratios of 2,4- 2,6-dinitrotoluene are modest (66 34).12 Dinitration of toluene using Claycop (copper nitrate on K10 clay), acetic anhydride and nitric acid in the presence of carbon tetrachloride produced dinitrotoluenes in a yield of 85% with a ratio of 2,4- 2,6-dinitrotoluene of 9 1.13 This method, however, requires a large excess of nitric acid, the use of an unacceptable solvent and long reaction times. The direct nitration of toluene to 2,4-dinitrotoluene using nitric acid over a zeolite P catalyst, with azeotropic removal of water, is reported to give a 2,4 2,6 ratio of 14, but full results are yet to be published.14... 

Amino-5-methylthiazole)(l,4,7-triazaheptane)copper(ll)] dinitrate was characterized by X-ray diffraction. There were two crystallographically discernible cations [(amtz)(dien)Cu] and four NOs ions in the asymmetrical unit of the structure. Dien is tridentate with mean Cu-N = 1.997(5) and 2.021(5) A in the two Cu-ions, respectively. The thiazole ligand is coordinated through its endocyclic N with Cu-N = 2.063(7) and 1.945(6) A in the two ions,... 

It is remarkable for its ability to take part in the formation of coordination cqmpds, such.as ammines (See Vol 1 of Encycl, pp A275fO some of these compds are expl, as, for example, copper complexes described here under Ethylenediamine Complexes . On neutralization with nitric acid it forms the expl Ethylenediamine Dinitrate (See below), while under other conditions it gives the expl Echylenedinitramine, which, however, is usually prepd by nitrating ethyleneurea. Other expl compds, such as Di chlorate. Diperchlorate are prepd from ethylenediamine... 

Furthermore, porphyrins react like extremely electron-rich aromatic compounds, comparable to phenol, aniline, or pyrrole. Central metal ions, in particular zinc(II) and copper(II), further activate them in electrophilic substitution reactions, l pical examples of the di- and tetrachlorination, mono- and dinitration, and most important Vilsmeier mono me o-formylation are given (Scheme 6.4.3) (Bonnett and Stephenson, 1965). Vilsmeier formylation of tetraphenylpor-phyrins gives mono (3-formyl products, which have been used to attach side chains to an imidazole end. Five coordinated metal complexes thus become accessible (not shown).
