Sodium Nitrotetrazolate Dihydrate (NaNT) Anhydrous aminotetra-zole (8.48 g, 0.10 mol) and copper sulfate pentahydrate (0.2 g, 0.8 mmol) were added to a solution of nitric acid (9 mL, 65 %) in distilled water (60 mL). This was added to a pre-cooled solution of sodium nitrite (20.8 g, 0.30 mol) and cupric sulfate pentahydrate (11 g, 0.044 mol) in distilled water (100 mL). The solution was maintained at 15 to 18 °C during the addition by means of a cool water bath. After addition, the solution was stirred for 30 min at the same temperature... 

Preparation of sodium-5-nitrotetrazole dihydrate The diazotization of 5-ami-notetrazole monohydrate (AT) in the presence of excess of sodium nitrite and copper sulfate gives a complex cupric salt intermediate [Cu(NT)2 HNT-4H20] which is then converted to the sodium salt [NaNT-2H20].

The CuCli-CuO promoted hydrolysis is not solely limited to thioacetals—a variety of acetals are also deprotected [21]. Treatment of 26 with the copper catalysts in acetone-water afforded the spiroacetals 27 and 28 via concomitant hydrolysis of the thioacetal and benzylidene dioxy and ethoxyethyl acetals (Sch. 7) [22], Copper(II) chloride dihydrate has also been shown to hydrolyze a variety of acetals [23] and trityl groups can also be removed in the presence of copper sulfate in benzene to afford deprotected alcohols [24].

Decomposition of model substances method The third method of calibration is by carrying out an experimental run using certain well studied model substances such as copper sulfate pentahydrate, calcium carbonate, calcium oxalate mono hydrate, potassium carbonate, sodium hydroxide, zinc oxalate dihydrate, and benzoic acid. These model substances show well resolved dehydration and decomposition temperatures over a wide temperature range.

Pentacarbonyliron (2.9 g, 15 mmol) is added dropwise to a solution of anhydrous potassium butoxide (1.68 g, 15 mmol) in tetrahydrofuran (70 mL) at 25 C under dry nitrogen. The color of the reaction mixture immediately changes from yellow to dark brown. The reaction mixture is stirred for another 1 h at 70 °C and brought slowly to 25 °C. Diphenylacetylene (0.44 g, 2.5 mmol) is added and further stirred for 10 h at 70 C. The mixture is brought slowly to 25 °C. The metal carbonyl complexes are oxidized using copper(II) chloride dihydrate (5.0 g, 30 mmol) in acetone (20 mL). Saturated sodium chloride solution is added and the contents are extracted with ether (2 x 75 mL), dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue is subjected to column chromatography [silica gel, hexane (2%)/ethyl acetate] to afford the pure 3,4-diphenyl-3-cyclobutene-1,2-dione mp 95-96 °C, 0.52 g (88%) ...
