摘　　要：以苯并噻吩为原料,通过酰基化反应,在噻吩环上引入苯甲酰基,制备了苯基苯并噻吩酮。通过高效液相色谱分析法,分别对微波辐射和传统油浴加热条件下的反应结果进行了测试,结果表明:当微波输出功率为30 W、催化剂为AlCl3、反应时间为15min、溶剂为DMF时,产率可达72%。该化合物的紫外吸收红移到359nm,作为紫外光固化涂料中的光引发剂,表现出良好的反应活性、表面固化能力及溶解性。A new kind of benzo [-b] thiophen-2-yl （phenyl）methanone was prepared by benzothiophene with benzoyl chloride. The optimum reaction conditions were determined. It showed that the yield of target product was 72% when the reaction was carried out under microwave irradiation （30 W） for 15 rain in N, Ndimethylformamide （DMF）. Further, the photo-initiated polymerization performance test of the title compound show that it can be applied as radical photoinitiators in UV-curing system. The UV-curable coating has good reaction activity, surface curing capability. And the release of benzene is also reduced.
