解説N,4-dimethyl-N-nitrosobenzenesulfonamide.C8H10N2O3S(214.25).N-メチル-N-ニトロソ-p-トルエンスルホンアミド, p-トルエンスルホニルクロリドとメチルアミンとからN-メチルアミドを合成し,それをニトロソ化すると得られる.黄色の結晶.融点62 ℃.アルカリを作用させてジアゾメタンの発生に用いる.比較的安定で室温で保存可能である.森北出版「化学辞典(第2版)
使用N-Methyl-N-nitroso-p-toluenesulfonamide is Diazomethane precursor.
純化方法Crystallise diazald from *benzene by addition of pet ether and store it in a refrigerator. It is soluble in most organic solvents and liberates diazomethane on treatment with alkali. Store it in the cold. [deBoer & Backer Org Synth 34 96 1954, Beilstein 11 I 29.]
