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.
