p-Nitro-acetophenone was prepared by diazotizing p-amino-acetophenone in fluoroboric acid solution and replacing the diazonium fluoroborate group by the nitro group in presence of finely divided copper as catalyst. Yield 55-60%; m.p. 76-78℃. Recrystallization from alcohol gave a product of m.p. 80℃.

從乙醯苯胺、醋酸酐與氯化鋅作用,經水解後製得對胺基苯乙酮。在氟硼酸水溶液中重氮化之,再在亞硝酸鈉的水溶液中以銅粉為觸媒,將此重氮團置換成爲硝基,即得對硝基苯乙酮。

p-Nitrobromobenzene was prepared from the sodium salt of α-p-Nitrophe-nyl-β-acetyl-hydrazine by bromination and subsequent addition of copper catalyst.Similary,α-p-nitrophenyl-pyridine was obtained by adding pyridine instead ofcopper catalyst.
