摘　　要：以苯基硼酸与对二溴苯为原料,在微波辐射下,以PdCl2(PPh3)2为催化剂,四丁基溴化铵为相转移催化剂及氟化钾和三氧化二铝的参与下,在水/四氢呋喃为介质的非均相体系中,合成了对三联苯,并探讨了辐射功率,时间,相转移催化剂和载体对反应的影响。A convenient route for the synthesis of p-terphenyl by coupling reaction of p-dibromobenzene with phenylboronic acid is reported. The reaction was catalyzed by PdCl2 ( PPh3 )2 using TBAB as PTC, with fluoride and alumina mixture in THF and water system under microwave irradiation. The effect of microwave irradiation time and power, dope and PTC on the reaction was also studied.
