(precursor of diazomethane1a)
Alternate Names: Diazald; p-tolylsulfonylmethylnitrosamide.
Physical Data: mp 61–62 °C.
Solubility: sol petroleum ether, ether, benzene, alcohol, CHCl3, CCl4; insol H2O.
Form Supplied in: pale yellow powder; commercially available.
Preparative Methods: prepared by the reaction of p-Toluenesulfonyl Chloride with methylamine, followed by nitrosation with Sodium Nitrite in glacial acetic acid.1c
Purification: recrystallization is best achieved by dissolving the reagent in hot ether (1 mL g−1), adding an equal volume of petroleum ether (or pentane), and cooling in a refrigerator overnight.1c
Handling, Storage, and Precautions: store in a brown bottle. Has a shelf-life of at least 1 year at rt. For longer periods of storage, it is recommended that the reagent be purified by recrystallization1c and refrigerated. Toxic; severe skin irritant; handle only in a fume hood.
