Aromatic dinitriles were prepared with excellent yields by refluxing the corresponding aromatic dialdehydes with hydroxylaminehydrochloride in 85% formic acid or glacial acetic acid.
芳香族二醛与羟胺盐酸盐在85%甲酸或冰醋酸中回流可制备相应的芳香族二腈。方法简便，产率高。

The radical 2 as an electron donor underwent a rapid photo-induced redox reaction in carbon tetrachloride leading to the formation of the corresponding piperidine hydroxylaminehydrochloride.
自由基2作为电子给体在四氯化碳中可发生光诱导的氧化还原反应，导致生成相应的哌啶羟胺盐酸盐；
