摘　　要：以TCC／SiO2（盐酸三甲胺三氧化铬／硅胶）作氧化剂，由不对称N，N’-氢化偶氮苯快速、有效地合成了一系列偶氮化合物。此方法在60℃下就可快速完成（5min），而且现象明显，后处理简便，收率高。Using the inexpensive, readily available and environmentally acceptable reagent TCC/ SiO2 （trimethylammonium chlorochromate/silica gel） as an oxidation system, a series of unsem- metric azo compounds are efficiently prepared from unsymmetric hydrazo compounds. This method has the advantage of being a green process along with a short time, mild reaction conditions and good yields. To the best of our knowledge, this is the first example in which unsymmetric azo compounds are prepared.
