新型酸性离子液体催化3-甲基-1-戊烯-4-炔-3-醇的研究

摘要

以3-甲基-1-戊烯-4-炔-3-醇为原料，新型酸性离子液体为催化剂，反应合成3-甲基-2-戊烯-4-炔-1-醇，考察了反应的条件及催化剂的使用情况，结果表明：酸性离子液体可以取代传统的酸性催化剂催化烯丙基重排反应，其中以双酸性中心的离子液体催化剂效果为最佳。%3-Methyl-1-penten-4-yn-3-ol as raw material,new acidic ionic liquid as catalusis, for re-active synthesis 3-methyl-2-penten-4-yn-1-ol,the study of reaction condictions and catalyst type,the re-sults showed that acidic ionic liquid may replace the traditional acidic catalyst to achieve allylic rearrange-ment,the acidic ionic liquid double center best effect.
