本研究主要以铃木-宫浦反应(Suzuki-Miyaura)中的C—C偶联反应为研究对象,使用四(三苯基膦)钯作为催化剂,将3-溴吡啶、3-溴喹啉、3-溴-5-苯基吡啶分别与苯硼酸、2-甲基苯硼酸、3,5-二甲基苯硼酸在甲苯溶剂环境中进行“一锅法反应”。反... 详细信息

本研究主要以铃木-宫浦反应(Suzuki-Miyaura)中的C—C偶联反应为研究对象,使用四(三苯基膦)钯作为催化剂,将3-溴吡啶、3-溴喹啉、3-溴-5-苯基吡啶分别与苯硼酸、2-甲基苯硼酸、3,5-二甲基苯硼酸在甲苯溶剂环境中进行“一锅法反应”。反应过程中定时取样,采用电喷雾-捕集离子淌度飞行时间质谱(ESI-TIMS-TOF MS)对Suzuki-Miyaura偶联反应的氧化加成过程与转移金属化过程后生成的中间体进行检测。研究表明:1)在氧化加成过程中,由于苯硼酸并未参与中间体的形成,所以在含有不同苯硼酸参与的反应中检测到的中间体质荷比相同,然而转移金属化过程后,由于参与偶联反应的2种物质不同,检测到的中间体不同;2)检测到的中间体同位素峰与预测图谱一致;3)使用捕集离子滴度飞行时间(TIMS-TOF)对检测到的基团进行离子迁移率检测以区分同分异构体,同时对检测到的中间体进行MS/MS分析,研究碎裂基团,利用TIMS-TOF得到的质荷比、离子迁移率、MS/MS等数据研究有机反应机理,可为金属Pd催化的反应机制研究提供参考。
