Description
技术领域
本发明属于有机合成领域,具体涉及一种将非活化端基烯烃选择性氧化为仲醇的方法。
背景技术
以空气为氧化剂将烯烃氧化成醇,是一种经济环保又高效的醇制备方法。目前报道的烯烃氧化得到的产物主要是酮类化合物,同时伴随着少量醇副产物生成。最近,等人提出了烯烃氧化为酮和醇的方法(Angew.Chem.Int.Ed.2021,60,14083)。作者以空气为氧化剂,以设计合成的Fe配合物为催化剂,将活化烯烃转化为酮类化合物,同时还有少量醇类副产物生成。近期,Studer等人提出烯烃氧化合成醇的新方法(Angew.Chem.Int.Ed.2021,60,8313),作者利用过量硝基苯作为氧化试剂。但硝基苯在后期分离困难,且属于易制爆化学品。基于此,我们开发出非活化端基烯烃氧化为仲醇的方法,利用非活化端基烯烃作为底物,以廉价易得的乙酰丙酮铁(Fe(acac)3)作为催化剂,利用苯硅烷作为氢原子供体,在室温下以空气作为氧化剂,以较高产率得到结构新颖的醇类化合物。反应具有很好的区域选择性,醇产物均为仲醇。
发明内容
解决的技术问题:本发明提供一种将非活化端基烯烃氧化为仲醇的方法,该方法用乙酰丙酮铁作为催化剂,在室温空气下进行反应。另一方面,本发明所使用的反应条件温和,有很好的工业生产前景。
技术方案:一种将非活化端基烯烃氧化为仲醇的方法,步骤为:将烯烃、氢供体和催化剂加到极性溶剂中,所述烯烃、氢供体和催化剂的摩尔比为1:2:0.1,置于反应器内,搅拌反应,反应结束后,经柱层析获得醇产物;所述烯烃的结构式为:获得的醇产物结构式为:/>其中R为芳胺基团、酰胺基团或苯酚基团。
极性溶剂体积为1mL,烯烃物质的量为0.2mmol。
上述R为-CONH-Ph-2-Br、-CONH-Ph-2-Me、-CONH-Ph-2-NO2、-CONH-Ph-4-Me、-CONH-Ph-2-SMe、-CONH-Ph-4-F、-CONH-Ph-3-Me、-CONH-Ph-4-Et、-CONH-Ph-4-COOMe、-CONH-Ph-3-CF3、-CONH-Ph-4-Et、-O-Ph、-O-Ph-4-Br、-O-Ph-4-Me或-O-Ph-3-Br。
上述醇产物为:
反应过程中采用TLC薄层色谱跟踪反应进程。
上述氢原子供体为苯硅烷。
上述催化剂为乙酰丙酮铁。
上述极性溶剂为甲醇或乙醇。取烯烃、氢原子供体、催化剂、溶剂、加入到反应器中,室温反应,反应通过TLC薄层色谱检测反应是否完全,待反应结束后,通过柱层析即得烯烃氧化的产物。
有益效果:本发明的方法中利用廉价易获取的Fe(acac)3为催化剂,配合氢原子供体PhSiH3,通过自由基反应,与空气中氧气结合,使烯烃一步转化为仲醇。提供了一个操作简单、产率高、经济高效的方法,具有重要的应用价值。
