Abstract

本发明提供了一种不饱和烃的卤化方法。所述卤化方法包括将不饱和烃化合物与N‑氧化物、卤源混合,得到卤化烯烃或烷烃。该方法无需采用单质卤素或卤素互化物作为卤源,而是采用廉价易得安全的卤源,能快速高效地对不饱和烃进行卤化,得到卤代烯烃或卤代烷烃。并且烯烃产物结构单一,均为反式结构,为不饱和烃的卤化提供了一条便捷的新途径。

Description

一种不饱和烃的卤化方法
技术领域
本发明涉及有机合成领域,更具体的,涉及一种不饱和烃的卤化方法。
背景技术
多卤化烯烃/烷烃是一类重要的有机合成中间体,后续可逐步进行偶联反应,将烯烃/烷烃修饰成不同的分子骨架。已广泛用于医药、农药、染料、香料、增塑剂、阻燃剂等及其中间体等行业,故其合成方法受到广泛关注。
目前已报道的多卤化烯烃/烷烃的合成方法有以下几种:
方法一:不饱和烃与卤素单质反应(Journal of Organometallic Chemistry,372(1989)183-186;J.Org.Chem.2003,68,10175-10177;Green Chemistry,2002,4,621–627;ChemistrySelect,2(32),10375-10378;2017)。
Figure BDA0003018976500000011
(X1X2=Cl2、Br2、I2、BrCl、ICl)
此方法的缺点是:使用的卤素单质不易取用,高毒并且具有腐蚀性。
方法二:不饱和烃与金属卤化物反应(CHEMISTRY LETTERS,pp.1357-1358,1979.;J.Chem.Soc.,Perkin Trans.1,1987,1017-1019;J.Am.Chem.Soc.2017,139,15548-15553)。
Figure BDA0003018976500000012
此方法的缺点是:需要使用当量的金属汞盐或碲盐。
方法三:不饱和烃与卤负原子在氧化剂条件下反应(Tetrahedron 55(1999)11127-11142,Synthesis 2014;46(02):251-257;SYNTHESIS 2014,46,0251–0257;GreenChem.,2015,17,3285–3289)。
Figure BDA0003018976500000013
此方法的缺点是:原料局限定较大;氧化卤化方法都只能对不饱和烃作相同卤素的卤化。
方法四:不饱和烃与NCS在三苯基膦催化下反应(Org.Biomol.Chem.,2013,11,1598-1601)
Figure BDA0003018976500000021
此方法的缺点是:只能对烯烃进行加成;只能进行二氯加成,无法实现其他二卤加成。
方法五:不饱和烃与氯化锂在四氟硼酸二吡啶碘鎓盐条件下反应(Synthesis,(3),270-2;1992)。
Figure BDA0003018976500000022
此方法的缺点在于:LiCl的用量大;四氟硼酸二吡啶碘鎓盐的价格昂贵;反应时间长达80小时。
综上所述,现有技术都有各种不同的缺点,或者原料受限,或者试剂昂贵,或者操作不便等等。
