(一)α-对硝基苯-β-乙醯肼钠盐溴化后,加进铜催化剂,即有放氮效应,产品为对硝基溴苯。(二)用吡啶代替铜催化剂,亦放出氮气,产品为α-对硝基苯吡啶.

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