The efficient At-nitration of secondary amines has been achieved by transfer nitration with 4-chloro-5-methoxy-2-nitropyridazin-3-one, a reagent prepared from the nitration of the parent 4-chloro-5-methoxypyridazin-3-one with copper nitrate trihydrate in acetic anhydride. Reactions have been conducted in methylene chloride, ethyl acetate, acetonitrile and diethyl ether where yields of secondary nitramine are generally high. Homopiperazine is selectively nitrated to At-nitrohomopiperazine or At, At -dinitrohomopiperazine depending on the reaction stoichiometry. At-Nitration of primary amines or aromatic secondary amines is not achievable with this reagent. 

Copper nitrate trihydrate occurs in nature as the mineral gerhardite.

Procedure B. A solution of copper nitrate trihydrate (1.2 grams, 0.005 mole) and excess (200% usually) amine were mixed in 10 ml. of 95% ethanol with a solution of 4-iminopentane-2-one (1.0 gram, 0.01 mole) in 10 ml. of 95% ethanol. The mixture was heated at reflux temperature for 3 to 4 hours, and the resulting solution diluted with water. 

Copper Nitrate Trihydrate, Cu(NO )2.3H20, mw 241.63, blue delq crysts,mp 114.5° can be prepd by treating Cu or CuO with nitric acid, followed by evapn crystn. It is an oxidizing material less dangerous than the anhydrous salt. There are also hydrates with 6, 9, 2.5H20 (Refs 1, 2, 4,... 

An alternative procedure described by Adkins is as follows. Thirty-one grams of barium nitrate is dissolved in 820 cc. of distilled water which has been heated to 80°. To this hot solution is added 260 g. of copper nitrate trihydrate, and the... 

Copper nitrate trihydrate (Cu(N03)2-3H20) and hydrazine hydrate (N2H4 H2O) were both analytical reagent (A.R.) grade, and sodium stearate (CH3(CH2)i6COONa) was a chemically pure (C.P.) reagent. These were purchased and used without further treatments. Distilled water was used as the solvent.
