Description
技术领域
本发明属于但不限于化学合成技术领域,尤其涉及一种氮氧化物或者硫氧化物催化的芳基卤化物的高效卤化合成方法。
背景技术
在有机合成中,芳基卤化物是广泛存在于许多具有生物活性的天然产物中(Gribble,G.W.J.Chem.Edu.2004,81,1441),同时芳基卤化物作为重要的有机合成中间体,大大提高了有机合成的效率(Neilson,A.H.Ed.Organic Bromine and IodineCompounds.In the Handbook of Enviromental Chemistry,Springer,Heidelberg,Berlin,2003)。因此发展芳基卤化物的高效合成方法是当前学术界和工业界的热点研究领域之一(Dagani,M.J.;Barda,H.J.;Benya,T.J.;Sanders,D.C.Eds.Ullmann′sEncyclopedia of Industrial Chemistry:Bromine Compounds,Wiley-VCH,Weinheim,2002)。传统的芳基卤化物的合成方法主要是使用卤素(Br2,Cl2,I2),但是卤素是一种高毒性、高腐蚀性、高挥发性的试剂。因此,化学家们发现了一系列基于氮原子的卤化试剂,比如N-卤代丁二酰亚胺、1,3-二卤-5,5-二甲基海因、三卤异氰尿酸等。但是由于其活性比较低,常常需要使用不同的活化试剂才能实现芳环的卤化反应。目前为止仍然缺少高效、高选择性、低成本、反应条件温和的芳环卤代反应。因此有必要发展新的卤化策略来实现芳环的卤化反应,为芳基卤化物的合成提供更高效的方法。
