摘　　要：文章以曙红为催化剂,研究光照条件下的卤代芳烃与频哪醇硼酸酯的C-B偶联反应。研究结果表明:用溴代芳烃摩尔分数为10%的催化剂,在蓝光照射下室温反应36 h,多种芳基硼酸酯产物的收率达到31%~60%;产物结构通过核磁共振氢谱(1H NMR)、核磁共振碳谱(13C NMR)和高分辨质谱仪(high resolution mass spectrometer,HR-MS)来确认。A simple,metal-and additive-free,photoinduced borylation of haloarenes by the alcohol-soluble Eosin Y was studied.The reaction system is mild,and reacts at room temperature for 36 h under blue light irradiation with 10%Eosin Y,and the yield of the boronated product is 31%60%.The product structures were confirmed by 1H NMR,13C NMR and high resolution mass spectrometer(HR-MS).
